Well for your current one I would have to see what are stocks and what isn't, because of what I can see so far, it's a background that isn't made in Paint.Net, and three different birds that are made in Paint.Net, and your name.
I like the mixture of colors, but its too plain.
Also, if you look very closely, you can see the beveled parallelogram that it's made up of. I like it overall, but from the looks of it, most of it could be done in a few minutes.
However... if that background were in Paint.Net, things would all be different.
