Fire Fist Ace

We see one great character here. Ire always shows us good times.
This pose always fits Ace's sharp personality, and it makes him even more sexy showing his bu-- back. The shading of his skin is really good, thought the darker parts could be darker so it'd increase the contrast and make the picture more beautiful.
It may be my critique eyes, but the first thing I notice was the hat. For some reason it looks a little too small for his head, plus the happy/sad faces buttons are missing (but this is a detail that can be ignored). The balls on the hat are too flat, it needs a little more care about the shading.
I can't see big mistakes on the anatomy, it's good, it's manly and it's sexy. And the tattoo, thought everyone knows OR HAD READ ON THE ARTIST'S COMMENT (right?) it's not the original, it fits him very well. Could it be our jolly roger?~
About the whole thing, it's a good pic of our beloved Ace and it deserves to be favourited.
