Thanks for resubmitting, but the piece still has the same color count issue!
And now it's 2733 colors.
After I looked more closely I see that there are many similar colours used in different places. Some just for two pixels. The art looks great but even if 147 is an acceptable number it is not justifiable in this situation. Please recycle some colours and decrease the colour count. You definately don't need as much for the art to look as good.
Hey there! There's 147 colours in this piece, which means you probably have some stray pixels, maybe from erasing? Would you mind removing them and reuploading? To see where they are, you can use PJ's Image Specs Tool here: Click
