Vision: I gave it 4.5 starts because I love the way it looks. I can see what you were going for here, and I think you actually nailed it. (The nose could maybe use some work, as a rougher appearance would make the fur and character more realistic)
Originality: Only 3 here cause there really isn't anything original about the pic. it's your standard head shot (BOOM). Not to say it's not bad... just lacks... well ... originality.
Technique: Ahhh, this is the category in which this submission was made for. I gave you 4.5 because I for one think you did an amazing job (especially looking at the old cartoon version and this new 'realistic' version). I LOVE how the back of hair came out... and I think some of what you did there needed to be applied to the front as well. I again, think the nose should appear rougher (or even a bit wet) to make it really complete and perfect. All in all (especially if this is your first time trying such thing out) You did a terrific job on it. *pets fur that has texture now*
Impact: Well as far as it's impact on me, I'd say it has a pretty big one. Shows me you are very capable of doing such things, and with such a great turn out on the first try, it can only mean greater things to come in the future.

(Please remember that I'm not a good artist and this critque should probably be taking with a grain of salt)
