Pretty good
.
First off, though, the darker blue is far too saturated! You should tone it down a little I think.
Also, those buttons aren't just decals, they're three dimension objects, and you should try to convey that in your picture.
I haven't looked at a SP in a long long time, so I don't know if the circles around the buttons are indents or just painted on there or something, but if they're indents, you need to make it look like indents instead of just a black outline.
Also: The ripping bit in the rules, that's about stealing art. Pretty much, if you haven't made it, it's considered a rip. As for edited sprites, I don't think it's against the rules, but it's generally frowned upon, and I doubt you'll get many critiques for 'em.
