Well what can i say apart from WOW! This is a truely beautiful piece of art, you put so much detail into all of your pictures and it is truely worth it. You have a great sense of colours and you have a very unique style which is just beautiful. I like this a lot as it seems as this character is running thought mystic sands, and the small but powerful detail you have put into the background goes with the actual subject very well. I love how the tails overflow onto one another, your anatomy overall is very good the only thing i have against it is that the front leg ( i think) should be a bit longer, but apart from that i just love this piece and keep up the great work!

I absolutely adore the colours and the way you did the fur.
However, the paw position, especially the front paws, is disturbing.
When a canine runs he places his hind paws to the sides of the front paws in the movement you pictured here.
Your front paws, however, go to one side and although I don't see the hind paws I guess they are behind the front paws, which I see as anatomically incorrect.
I tried to make a redline to explain what I see there because I'm better with pictures than with words. I hope you don't mind.

It's not very accurate but I only tried to show the leg position which I think is right.
