Jumping shroom

so this is a bit of "pixel art" im bloody proud of, please take the moment to download it and zoom in, and see just how many different shades and colours are in there.

this is a jumping shroom, im doing the sprites for a game bobb is making, which you can see here - [link]

this was all done in paint, it took hours, i know its big but that's an acecptable size, I'd love some feedback on this, specially from you fantastic pixel artists out there.

origanal design can be seen here - [link] that's what i made this sprite based on
