haha dude this is sick! awesome idea.

 Im not too sure about the front legs, and the colors seem too grey-ish, as I recall, it resembles a green and grey-ish color.

 Thanks for pointing that out, I'll be fixing that up soon.

 The hands are a little hard to read, I'd suggest adding a little more shine to them. Same for the feet, as they almost blend in with the shadow.

Otherwise, nice proportions and execution.

nice one!

 Thanks for the comments! :)

Very good looking!

 Very good & fine work ! 

Very sharp sprite! Excellent job.
