Professional quality. This scene is really awesome... though, I don't really see the point in making that sort of thing, for someone as good as you, since it requires only a good control of photoshop, and not your talent.
But back then i was just started with photoshop and i was very interested in space art. Now that i do paintings, i dont do space art very often anymore.
I do make space scenes where i actually paint the whole thing including planet. I will submit one soon.
