needs more depth. composition is wrong, Good concept. I will add more to this post soon. EDIT: It needs more depth (oh wait I said that earlier.) The "planet" just looks like a circle with light around it. and the atmosphere is just a gradient or a bunch of airbrushing. It would look much better if you put more detail and make it more realistic. -
I would have to agree with Acrima. The explosions are kinda random but I still think the piece came out pretty well. I wish people would realize that you can do alot with GIMP and you've shown a perfect example.
