Here's my current work (I cannot really say it's a work ;) ), Jojo l'escargot (Jojo the snail) :



Any c&c welcomed...

(The thing at the left of the snail's house, is a post-it)

Now colored...

i like the way the sign is made, but i dont like that everything else on jojo is very flat

try to visualise things in simpler shapes and shade them likewise
like, the head and the shell are balls

then, look up a shading tutorial (can be painting, drawing, pixelart. w/e, because we only need the shading part) then find where they shade balls, and apply that to the pixelpiece
