Here is my critque

--
Pros: Very good detail, nice anatomy, well-done pose, and the collar is excellent. I love the markings on the dog, very well-drawn. Good shading and lighting on the subject.
~
Cons: You could use a little more fur detail, not so blurry. The rug and background also should not be so blurry. Might be just me, but the shoulder area could use a little thickening. The eye dots wouldn't stand out so much in real life. You did a good job on the head when making it look against the rug, but the rest of the body looks a little like it's floating.
~
Overall: A nice picture, good overall composition and appeal. You could use some practice, but I know most is just from Oekaki's weirdness.

Keep practicing and you'll do great! I hope my critque helped!
