The problem is you may be a 3 meters high minotaur, with 1 in charisma and 1 in logic, your target will probably think you're the big silly guy, lot of muscles yeah, but not hard to fool (and it's not totally wrong).
I think you should take a lot more specialisations. For example, intimidation (physical), because you ain't intimidating at all when you're not facing the guy. I wander about your combat skills too. Why did you take the melee group ? I mean, what does it exactly bring to your character ? since you're good with bare hands, you could just have taken the unarmed combat skill up to 5, specialized it in a martial art (boxing for example), it's still less expensive than the melee group, and with the saved BP, you can buy the martial art advantage twice, so you get +2DV to your unarmed combat. Your melee groupe costs you 40 BP for 4 dices. The unarmed skill up to 5 + the specialization + the martial art quality taken twice, it costs you 31 BP if I made no mistake. EDIT : Mistaken : 32 - So you'll be more effective and you saved 9 BP - EDIT : 8. It's two specialization and a 5 point advantage - EDIT : and two maneuvers, not a 5 points advantage. Two specialisations ? hmm, for example intimidation "physical" and Heavy weapons "autocannon" ?
So, you get 3 more dices and +2DV in fighting with bare hands, you don't have to carry that obvious axe, and you get 2 more dices on both your intimidation and your autocannon, and you still can choose two maneuvers (and one should be "finishing move") - or take something else with the 4 BP left.
Note that I don't think the autocannon is a good choice, too much specialized weapon and unless your GM is very lazy on security, you'll nearly never use it, but, why not.
Take a smartlink too. And you MUST have two IP. One IP sammies are for veterans players who want to try the "hard" mode.
Try to apply this way of thinking to the rest of your character, and I think you can make him easily 20% to 50% more powerfull without being overpowered.
I think too a player should never never let an attribute under 2, unless he has a veeeery good reason for it (like 1 in agility for a hacker in a wheelchair), but that's my way of thinking.
