It's not easy to critique more experienced artists, but here it goes. The eyes are the best part IMO because that's where attention is immediately drawn. The green and blue mix stands out against shades of orange. I like how you used multiple colors instead of just oranges and reds to shade the fur. I don't know how you made individual strands of fur either, but the amount of detail is amazing. It's obvious time was spent on this. Everything is all balanced out too. I really can't think of any improvements that would need to be made with it.
