Nice cat! very stylish. looks like something out of a cartoon! it's very well shadedl. and yes, blick's sugestion do add to it! I think it looks good. the only thing I could put my finger on is the fact that it looks ( to me ) a bit like a mask. like if it had no depth. but that may be of the position of the light. front light tends to make things look flat.
take care,
Kaz
