The angles and curves look jagged and messed up, they could use a bit of cleaning. And I think it would look good with a little reflection in the water too, since it seems like very calm and clear water.
Maybe you should make a blue transparent over the lower parts of the support things in the water.

This looks good. Maybe there's a bit too much cyan on the chain links, it looks a little weird.
The second picture might need a bit more detail on the two big houses in the foreground, which also seem to be a bit out of perspective.
That's all I come to think of right now.

This is my first post here, and this is also my first real attempt at making a sprite.


I know it's bad to use an even number of pixels, his legs and the chest muscles look messed up, but his face didn't look cool when i tried to make it smaller. I made it using mspaint and graphicsgale, from scratch. I mimicked the claws from a RpgmXP sprite with similar claws.
He's gonna get a helmet, a loincloth and a couple of hands later.

C&C and advice apreciated.
