Excuses for the quality, it was taken with a webcam as the good scanner I used to use is no longer available.
(EDIT: now with proper scan.)
This is the longest piece of 'art' I worked on in quite a bit. I was going to use watercoloured pencils and I did, but I couldn't use the water since the paper was so thin it got soaked by even just a little. The grey-ish thing beneath the Yoshi is supposed to be a rock, even though it might not look like one.
Things I see are mistakes:
-No watercolour. (...)
-His left shoe is really much smaller than his right one.
-The background doesn't look natural enough
-The shading isn't smooth enough
- some bits (like the colour of his right shoe) stand out too much whereas other parts don't.
-the overuse of the colour black made it look like he is smeared in oil.
