My Corgi

This is a truly amazing piece and it at first made me think of people riding polar bears (due to the corgi's fur color). I love that you caught the natural expression of a corgi as well. The background is stunning too.
The only part that bothers me is the person on the back of the corgi, he/she seems out of place, my only guess that would help would be to fade him/her a little like you did with the effect on the foreground, like have more of it going on upwards. I also feel like the person's expression is too neutral, if that makes any sense, like a little smirk and slightly narrowed eyes if that makes any sense...

Overall, this piece is quite amazing and I'm quite interested in what you create next.

(Sorry if I'm not making sense, my brain is a little jumbled right now, I'm getting over a cold)
