Thank you) I'm agree with your opinion about second green - i've fixed him for challenge palette, it was one color i could change without strong corruption. I have to mind this once more

It's interesting how he seems to have a spring in his step dispite being immobile.  I quite like the character design.  I would advise spreading out the shades a bit more.  What I mean is that the second brightest green should be a bit darker because it's hard to make out from the brightest green.
