Look, well done for giving it a go and posting it out there for all to see. Keep in mind; even the freelancers who have published work get the occasional tough criticism. Putting your personal work out there requires thick skin, but also an honest self awareness helps so that you can work out what feedback is useful, and what feedback is someone giving you are hard time because you didn’t tick their personal boxes.
So, that said... ‘Who thinks my character has potential in a canon novel’... in the world of the internet where anything you say can be misinterpreted... this came across slightly arrogant (it’s like you’re asking for praise) and asking for tough criticism. After all, a personal player character background, or just plan fanfic, they don’t need to meet as high a standard as what we would all hope from actual canon published works.
Now, the actual fiction you wrote. ‘he overcame by being by far the smartest child in his class’. Without even looking at your profile, I would say (as a guess) you are from a non-English speaking background, which makes the general quality of your fiction quiet remarkable. However, it does, in my opinion, show in your writing with the occasional grammar errors and a statement about American celebrity. My guess is that you have spent some time in Europe, you write like my French and German friends.
The Dodger link seems unnecessary. If ‘Stierlitz’ was connected with Sean Laverty, the connection is possible from there, but as written it does seem unnecessary and doesn’t add value. Try to focus your character. If it doesn’t give us a new insight into your character, it should be removed.
‘as no school yet offered him the education he so desired, which was about the Elven people’. I have concerns with this statement as have others. We are talking 2011, so the concept of an ‘Elven’ people does not exist except, perhaps, for the immortal elves, and they keep their cards close to their chest. So, in its self, this statement makes no sense. He cannot have desired something which did not exist. It’s nice that he felt connected to 12 month and younger babies who just happened to have pointy ears.... Thank god he didn’t watch lots of Star Trek and then refuse to go to college because they didn’t offer a course on the Vulcan people... (joking... remember what I said about thick skin...)
Note: Your tense changes frequently, from past tense to present tense. It can be... disconcerting and distract people from being caught up in your fiction.
‘However, no government had yet given rights to metahumans, so he started his first stint of crime’... actually, this does not make sense. In the period 2010-2020, most ‘elves’ are aged under 10 years and they all think is a genetic condition. As an adult, it’s too soon for people to relies that your character is an elf and not a ‘human’. So he has rights.... Goblinisation is when it gets nasty... At least in my opinion. Instead, I think you focus on the chaos in Europe at this time, with economic collapse, Vitas plagues, the Black Tide, and frackin Dragons fighting each other in the skies above the cities.
‘ In 2029, moments after the first crash, he began his Matrix reporting,’... The Matrix doesn’t exist yet. Echo Mirage need to defeat the Crash Virus, and the Matrix needs to be built. Give yourself at least a year, maybe more. No need to be cutting edge on everything. Your character is already a spike baby, they don’t also need one of the first to use the Matrix.
‘yuppie’ is a dated word now. In 2029, I would be surprised to hear its being used. When writing fiction like this, it can be challenging to avoid writing in a way that becomes ‘dated’ quickly.
‘ In 2061, he stood strong with metahumanity, when goblinization started.’ Do you mean 2031? Also, what does ‘stood strong’ mean? He joined the orcs and trolls in the camps? He protested? Write harsh reviews on government policy in the Matrix chat rooms? Oh.. are you referring to Surge?
‘Although slightly cautionary, he and other Stierlitzes’ um... other Stierlitzes? Have I missed something? There appears no lead up to this statement, and when first read, makes no sense.
‘Several thousand people scattered all over the Russian- and English-speaking world (which is pretty much the whole world, is it not?) claim to be Stierlitz on a daily basis simply to try and up their social democrat street cred’... ahh that explains the previous statement. But your ordering is not good here. The first statement still reads wrong, even if it is explained several paragraphs later. Also, a little bit surprised that the ‘social democrat street cred’ is worth that much. Maybe in Europe, but not in the UCAS. At least not in the canon fiction I read. But political spectrums have changed a fair bit in the world of Shadowrun. Not sure if anyone has spent time analyses the new political parties that much to see where they fit in the old fifth world thinking.
Ok... now for my real criticism and answer to your question. In my humble opinion, your character is not ‘canon’ worthy. Why? Because what you have written does not grab me and make me want to know more. I’m surprised I’ve even written this response, but I felt your efforts deserved some feedback and it’s obvious (perhaps too obvious) that you have put a lot of yourself into this character. But it’s so dry. It’s not very interesting. Where are the hooks, something that makes me want to know what happens next? Your character is going nowhere, has no enemies, no major regrets, no need for redemption or retribution. No grand crusade that drives him through the ages, no great purpose, nor is he petty, vindictive. He's bland.
Try writing fiction, actual scenes where your character ‘does something’, talks, breathes, lives. Currently, his well thought out, but very 2-dimensional. If you care, but your passion into giving him some life. Oh, and don’t ask if his ‘canon-worthy’, let someone else tell you that.
