Very cute! Nice character, and I like the way you did the shadow thing on the background. There are a lot of things you could work on, though. You should keep practicing cat anatomy; a few things look off ([link]). A few things you might want to do in the future are using a smaller brush and not using only the airbrush tool to shade. It's fine for softer shadows, but use a harder brush too for certain areas. You also might want to use different colors in your shadows besides just black and white. These are just style choices though, so you don't have to listen to me. Overall, cute picture. Keep up the good work.
