Just a few quick notes
-You got pretty much everything spot down! Nice!
-I would like to see the fore shoulder-muscle shortened to look like it does in Hiccup's drawings sorta.
-The eye should go down more
-If you look on the JBDs official lines, you'll see barely and excess muscle behind the foot where the base paw pad should go on a dog.
I'll add you and you can change and move layers however you like to.
