Ok, I'll attempt to write a critique. It's only my first one, so forgive me if it's not the best.
Vision: Overall the visual of the picture is not bad. The lines are smooth, and not sketchy. You can easily tell what the picture is, a cat, and the anatomy is fairly decent.
One thing I think that could be improved is the eyes. The eyes are a bit large for those of a cat, and they seem to be unusually far apart. You might want to consider making them a bit smaller, it will look more naturalistic.
Second of all, one thing that needs improvement is the composition. Your picture, even if it is well drawn, is rather boring. Your cat is in an average pose, right in the center of the page. (I know I've been guilty of this too). It would be more interesting if your cat seemed to be doing something more, or interacting with the environment, rather than just sitting on the ground. Try considering interesting situations so you can practice drawing him/her from different angles.
Originality: Overall it's not that original. I've seen pictures like this a million time before. Same idea, different cat. Try mixing it up a little bit, and adding something unique. Again like I said above, try considering more interesting situations so you can improve the overall anatomy.
Technique: For the base of the drawing, I feel like the technique is ok, but it seemed after laying out the preliminary basics you stopped. So the ground is a solid color, the sky is a solid color, the clouds are a solid color. You get the point. I feel like the coloring could have been a little more complete. Try adding shading (I do see small hints it on the cat), but try adding it more to the environment as well.
Impact: Overall the picture is ok. It doesn't really impact me in anyway, or make me feel any certain way. It's just a cat, in a field, on a sunny day. Your skills are good, but the main idea is lacking. Try to really use your story telling skills to tell a story, rather than just paint a picture.
