@des: thr shading of the suit really makes it hard to distinguish his tentacles. Sure, we know it's there, but for some reason the blue dark shading of the tentabkes makes it feel a bit obscure, as if we know it's there, but now we have to actively look for it since we see the dark blue. Meh, either that, or a general unbalance of light/dark in the thing. Then again, it might look better when animated.
Also, I'm not sure if the sketch thread is the perfect place for pixellated art; i think we have a thread for that in the pixels section
EDIT: I find it extremely funny how the higher it is in my line of vision, the blacker the clack becomes, while the lower it is, the black becomes tinged with the light green-blue color
