Wolfy Face sketchdump

Some sketches of Randolph in his tame wolf form (as in not the crazy flipped-out version with the munchies for human flesh). The top 4 sketches are older while the rest are more recent.
Since Randolph maintains his human mind during "tame" (gotta come up with a better term for that) nights, I decided that he should emote like a human as well, prompting me to practice some expressions.
My goggy inspired sum of dem

I need to brush up on how to draw wolves! (especially the anatomy, gargh). If anyone has some crits pertaining to how my wolf-drawin' skills are, please contribute! Keep in mind that these are pretty stylized, but even cartoons can have glaring flaws compared to the subject they're modeled after, so I'm willing to take suggestions.
