Yes I agree with smk, not everything has to be extremely detailed, simple can be good as well.

That's pretty harsh, I actually liked the idea, and the execution is nice and simple. This man is an artist, try seeing the world through his eyes!

Man, it is not fair NOW - not fair to those who really worked and made some great pixels and animations. It is really, really weak work, dragging level of whole challenge down (as well as level of your own gallery).

Have guts and improve it now, not later (which may mean 'never'). You can.

I can always rework it later. Wouldn't be fair mid-contest. XD

Clever idea and I agree that eyes would of added alot more.

I think it needs some eyes. 

I think that it is a nice idea, but artwork itself needs heavy improvement. Black could be used in the sprite as outline rather than just BG.

I see youre trying to be creative, but as Photocopier said, the transparency doesnt really do all that much

the transparency as a colour doesn't do anything though, most people who used it as a 3rd colour actually made it do something.
