It kind of depends on what kind of art you were supposed to be creating, but overall I love it. I really like the blue and I think it's very creative and nice! I think you should turn it in.
I did something like this where I had a coffee cup on a little plate with mouse coming out. I got a 100, but this looks even better. I`d say nothing below a 95. This is due to the quality of the lines. They are smooth and even, not wavy or just poor quality in the line. The overall coloring is fantastic, I see a little blending going on. That is not a very easy thing to do. Back to the coloring, it is not to light, nor to dark. Knowing from past work like this, the handle of the cup is very important, you nailed that, the overall shape of the cup is well drawn. Finally the cat. It is well drawn, even lines, smooth line in fact. The mouth and eyes are done to great levels of detail. The size of the picture fills up the center of the paper, the only really different I`d do is just make a background. My teacher say use the whole page, or most of it, which you did. Whether with a background or not, You will make a 95+.
