You're still using the old SR4 base costs for your adept powers, rather than those from SR4A, where some of them dropped. Improved Attribute is only 0.75 now, and Improved Reflexes is only 2.50 now. So you could get (for example) Agility Boost: 1 to complement your Improved Agility, and an extra level of combat sense.
Purely a fluff, rather than crunch, quibble, but I have a hard time imagining a Ruger Super WarHawk in a hidden arm slide. I just picture that gun as being way to big to be concealed against someone's forearm.
From a crunch perspective, I have to ask - do you really need a bonus to full parry, when you have combat sense, as well as full defense for free? Because Arnis de Mano and Sangre y Acero could give you +2 damage value instead, which I think would be a lot more useful to you. I will add that the Set up maneuver, as written, is all but useless. It essentially trades what would have been a successful attack, for a bonus to your next attack. I would consider replacing it with Disarm or Riposte.
