The cat is very successful, you knew transcribe his expression of curiosity. In addition, we clearly see the fur, we say a photograph! One can easily guess the softness of fur. His eyes have nice colors (it seems like amber). However, I think the background is a bit monotonous, you may have to add some details of another color to "settle" a bit (for exemple you can paint green leaves). And the red part of the cat's head is "masked" by the color of the background. Otherwise congratulations again for your work, it's a nice work for a nice cat!
