Much improvement there Gilly. :] Some advice. When you draw the upper half of the muzzle to make it look 3D aka the line going down the head, erase parts of it and bliend it so it isn't as visible. Also the right eye where the muzzle is mostly covering that side,shade it more.
Other then that amazing job. You have improved
