I think this is one of the best examples to show that you don't need many colorful details to let a drawing look amazing.

You perfectly got the dogs lineaments and it really seems to look into your eyes. Especially love the snout, it looks really authentic and realistic, as also the eyes do.

You used the perfect colors and the perfect placed and got a composition of naturalness and fantasy in the perfect way.

The drawing lets you mentally getting into another world, you want to touch the dog and feel his fur.

You're a very talented artist and PLEASE keep doing your work as well as you did until now!
