This work really caught my attention, I'm really liking what you did with the colors here - that contrast between the blue sky and the orange tones of the fire, really beautiful!

I do see some mistakes, mostly in the anatomy. I think some have already been mentioned - the problem with the foreshortening of his left leg & shoe, and the weird positioning of the arm.

But I also notice that you put attention on the muscles of his torso and arms, but his legs seem to lack a bit of shape - I'm far from good in anatomy myself, but there seems to be no calf muscles. That part would be really easy to fix!

I'm really loving that background, with the clouds of smoke, the water, the fire... but I'm not too sure about the lighting on Ace's body. If it's a blue sky day, it would seem that the shadows are a bit too dark - like pertaining to a sunset.

I know the fire is giving another secondary light, but the light of the sun should cause some lighter reflections on the skin also. As I said, I'm not too sure either, because supposing there's more fire on the left side that we don't see, I guess we could get this lighting too!

Overall I think it's an amazing painting, and I'd love to see more like this from you. The atmosphere is just... ace. ;D

The first thing I noticed was his face, it's pretty scary and mask-like, his skin tone is quite flat in general. The pose looks strange and awkward. His left foot is too big and weirdly shaped, even taking into consideration foreshortening. The position of his upper body doesn't match the way the character is seated. The colour balance is off as well, the entire pic is too saturated.

The theme is pretty funny, but the style doesn't suit it, I think a simpler approach would have got the message across more clearly.

On the bright side, the lighting looks great, especially the effect round the flames. I like the background and the mast, it's well painted and nothing looks out of place. The overall composition isn't terrible either, no one element dominates nor is too central. Overall, a great picture.
