You already got 3 defensive skills, which synergize very well. Good! But maybe you want a fourth one as a close combat fighter, like Combat Reflexes.
Further, you need another skill to boost your melee damage on higher levels. Damage Lore or Combat Discipline are your choices.
DL incereases chance to inflict secondary effects like fire and poison damage over time.CD increases damage of your combat arts and reduces regeneration time. (You need to put your CAs in combos, but 1 CA Combos are viable.)
Last, Blacksmith/ Enhanced Perception + Bargaining do well on a 1 Aspect character. If you do your most damage with weapons, they might as well be good ones and better armor is always nice.
