I took a look as well.. I'm more of a riggger aficionado so I thought maybe I could add to Reaver's advice.
Honestly, he pretty much covered it though. If you want to be a successful blackmail artist you'll want to address being able to leverage your data, not just collect it. Negotiation, especially with a specialization in Blackmail, is something that's pretty much a no-brainer of an improvement to the character for meeting your concept. I'd also suggest/recommend the Software skill: you can clear up grainy footage to better prove misdeeds or even maliciously edit in misdeeds where none actually existed. (Every blackmail artist should be proficient with Photoshop...)
With skills as priority A, you shouldn't have a hole in skills like that... you have lots of points to move around. Eyeballing it, it looks like you spent your 10 group points in 5 stealth, 3 engineer, 2 athletics. The investments in engineer and athletics aren't doing you much for you, tbh. Your drones will do the sorts of things Athletics is covering anyway, and you're running virtually stock drones. Ones that are cheap enough you can possibly just replace rather than repair them. If you want to keep the mechanic skills just to cover future modding, I'd look at dropping Engineer down to 2 and buying Electronics instead. The points you already spent on Hardware could then go into Negotiation (Blackmail). I'd also suggest finding a way to add the Sensor Operations specialization to your Electronics Warfare skill. As a rigger using drones to collect data, that's your primary skill and specialization.
Unless your GM is giving you special permission to have beta/deltaware... you'll have to downgrade those as Reaver mentioned. That'll free up lots of money, and here's some suggestions on what to buy with that freed up money:
A drone rack for your Motorcycle (it'll be worth it to be able to transport your drones around...)
A fake SIN & fake permits (don't forget to buy Driver's, Drone Pilot, and assorted weapon licenses)
A datajack isn't necessary as a VCR already gives you a DNI, but its Noise Reduction is ever-useful for riggers
Might even look at upgrading your VCR rating, if you plan on using vehicles/drones for things other than intel-gathering
Certainly look at the cornucopia of options regarding sensors. If collecting footage/data is your specialty, this is where you'll want lots of specialty options. (a couple of spitball suggestions: Laser Microphone, X-Ray, Ultrasound, Radio Signal Scanner)
With regards to qualities: Lose Acrobatic Defender. Even if you keep the 2 skill group points in Athletics. Spend those points on a quality that helps you do what you do in your niche (drive drones, make perception tests, etc)
