I am pretty young, but I am KEEN on graphics-making. I work with Paint.NET and Powerpoint (it's suprisingly helpful with some effects). I do manipulations, photo-editing, pixel-art, line-art, and general Paint.NET designs. I love getting projects, so leave a comment! I plan on doing a couple tutorials. Thanks for visiting.
It looks good, impressive. Couple of scientific/graphic critiques:
-Less solar flare, your's is a too thick and dramatizes it
-Earth doesn't look aerial (Needs more white and land)
-Colors are a little superficial
