Not bad. The body is on the right track for the species type and the fingers and toes look decently rodentish. I'd say the ears could be worked on, they don't appear to be the same shape. The face should also be broader, rather than having than thin canine-like muzzle. Eyes might also benefit from being further apart. Still better than going with a generic red fox fursona.

I agree with the eye part, and I think the reason the ears look like that is because i was trying to draw him looking from a specific angle. So it may appear that his ears are different sizes when it really isn't. Still getting the hang of perspectives :P I don't understand what you mean by broader though, do you mean bigger, bulkier, or more rounded? I'm just curious

That's an example of what I mean. On yours, there's a long, narrow snout for a muzzle; basically his face and nose area are two distinct shapes, similar to a canine. On the image above, it's kind of more subtle, the head more seamlessly turns into the muzzle. Admittedly the image above isn't designed like a completely realistic mouse as the face is blunter than usual but the basic idea is that on rodents, their face and muzzle tend to be one continuous shape with subtle differences.

Ah ok, I see now, thanks :)
