Love the composition of it, as in the game, has a very pirate assassin feel to it. The costume really is pulled together by all of its individual parts.
The work on cosplay is quite superb, the shirt and shoulder look to be made of a very thin leather or just pleather, good stitching on the costume overall, straight lines, no bunching or bulges.
The weapons look good but the wooden handle grips have a very plastic look, too highly polished, but that could just be the exposure of the photo.
only thing I could see that could use some attention is the beld, its seems to jut be a single strip of material, I would double it over and give it some nice decorative stitching to just give it a bit more detail then just a flat strip, it would also give it strength.
