Wow that's not bad at all, especially for your first. You've got a lot talent and potential, keep it up =3

Thank you!

Nice work on the muzzle, dude! I'm completely self-taught as well, and one thing I found to be extremely helpful to direct-referencing Disney characters from screenshots of the movie (for me, Bolt. For my idol {Fluke}, Balto). Do this and pay careful careful attention to every single detail and what you do. With this, you'll learn head proportions :3
