It really is.
The number one thing I have to ask is; Is it suppose to be on it's side like that?
If it is then I think it would look better in portrait layout.
The secoint thing I need to address has little to do with the art its self and more about your presentation... again.... The lighting seems dark go to the Art101 account and read this; http://art101.newgrounds.com/news/post/314936 it will help you with taking better photographs of your paintings.
Continuing with the critique is the bears could use a little more definition. The two of them tend to blend a bit.
The lack of a full background in this seems to work this time. The background has a simple but abstract appeal to the painting.
the composition has a good feel to it.
over all, a couple of changes to the presentation would do some wonders.
Keep practicing. As I told you earlier, drop by the Art Forum for some more critique and exposure.
