Final Fantasy Hacktics

I wanted to make a sprite that was close to FSN gilgamesh. Tell me what I can improve.

Edit :I wasn't satisfied by the result. I decided to restart a bit. I think this time, it's a bit more like the model.

Hello,

       The nickname Takeno. I decided to join after playing the CCP patch (it was interesting to shape the char with those new jobs). My skills are a bit limited (I'm interested in sprinting* or testing) but my love for this TRPG isn't.
I hope to learn some small stuff in order to realize some (probably) interesting idea I have.

Greetings

                                                                      Takeno

Edit: Sorry for the typo, I mean "spriting"
