Oh?
sweet designs, NB, although I have 2 complains:
The first Robot (Skate Man) seems to have way too big wheels which makes his standing pose look kind of awkward. it's not bad spriting here, but rather a minor design flaw ; ) I also have a hard time to see the distinct colors of him because I am partially colorblind. Those 2 shades of red and green do not match to another, in my opinion.
The helmet looks much better, it reminds me of Proto man's and Turbo man's, but that's totally OK since it doesn't look copied at all.
As for shark man, while his color scheme might be unique, I'd rather prefer a more traditional Shark man. The armor on the other hand is very cool, although the helmet and that back fin make him look a bit like Sonic-the-sand-color'd-hedgehog man.
I like the gun design. Have you tried to attach the little fin on top of it to underline the skark resemblance even more? That said, awesome interpretation of Shark Man!
The Eye Man (Ocular man? ) defenitly looks great. Only minor flaw i see is the right shoulder pad. it just doesn't look that well attached to the main body. The rest however is totally wicked!
