Wow, very impressive.
You seem to have good animation skills along with lighting.
One piece of advice is:
When your character looks like a cartoon,
try to keep the motions less fluid and more on the snappy side.
You basically have to recreate the cell animation style but in 3D.
If you don't know what I mean, youtube my favorite animated character "Foghorn Leghorn".
wow..many thanks for the tip..sure. i know what you mean..! and adding to that "Foghorn Leghorn" is animation survival kit..which is awesome.! for this matter
