It is AMAZING! The fur is just so beautiful. I'm not sure I'd be able to do that. I'm really impressed with your limited palette! Perhaps that's why the piece is so unified. I just love it! Good luck making the professional leap, but I don't think you need it! ;)
Yes, I agree with everyone else. This is certainly way above average. It's just beautiful. The color, the composition, the strokes, the details, the dog's expression, all perfect.
