Hm. I've never written a critique before, so I'm going to try it out on you xD Hope it's okay!

First I want to say that overall this is an amazing piece! Everything about it is just awesome; I'll go into detail in a moment.

Okay, the vision. Everything is placed very nicely- it flows and the eye travels nicely from focal point to focal point. Great movement in here too!! Also, I absolutely love the technique you used here! With the square that the drawing is in, and then it looks like it is raised above the white piece of paper... lol it's hard to explain but you know what I mean... hopefully. Anyway, I also love how the tail is poking out of the drawing almost. Great technique!

Originality: I have seen this technique around, but it never gets old! I love the way it looks, and the 3D effect is something I don't see often at all! However, you know, the wolf and the pine tree... a little overused. But I love the trees in the background, and the pond is very cool too! Water seems difficult to draw, but you've got it down pretty good. However, I think the splash is a little under-exaggerated. I think it would look a bit better if the splash was more scattered, and individual drops were kinda flying everywhere.

Technique: Once again, very cool. I absolutely love how you draw fur texture and all around shading. However I think your anatomy could improve a bit. For example, the hind end looks a little too big and... pointed. I think it would look better if it was cropped and rounded a bit. Um... that's pretty much it, though, as far as anatomy goes And once again, the 3D paper effect is awesome

Impact: I think the drawing-square-against-the-white-paper-with-3D-effect-thing (lol) really adds to the impact of the drawing. it makes it very interesting to look at.

Alright, overall, this is an awesome piece- I love your style!
Anyway... I hope that was okay and it had enough feedback!
