I agree with Herr, also a couple other notes I see: You have all three of the athletics skill group skills at a pretty low level, so could just use your 2 skill group points there in place of gymnastics, running, and swimming, that'll free up 4 regular points to spread and take care of your 2 group points into actual skill groups as per Herr's note that blades and tracking are not groups in their own right. Also you have regular ammo for the slivergun, and I may be wrong, but I think it only goes flechette rounds, which is what is listed in the gun stats.
As for skills, it looks like you used the full 28 on base skills, assuming the 0 in blades was supposed to be a 5. However, the specializations each cost a point as well, and you've got 12 from my count. Fastest fix would be to drop each skill by 1 if it isn't already at 1 and keep the spec, which then leaves you at 5 rating 1 skills (assuming you go with the skill group advice above) and 4 points freed up from the skill group rework. Ultimately, you keep everything the same, but lose one spec on one rating 1 skill, and boost running and swimming up to 2 as part of the group.
Last note, if I remember correctly, acrobatic defender replaces willpower with gymnastics for full defense, both your wil and gym are rating 2, so not really a gain there, did you mean to take agile defender? That would use agi rather than gym for full defense.
