http://kriptiq.deviantart.com/art/ODYSSEY-67882358 C&C welcome. Tryin' to get better at these, I know this one's pretty plain.
Thanks for the comment Calabur, I originally had one but it didnt look right with the lighting I have on the planets. meh
The planets stick out too much. Try blending them in a bit more (they are a bit too sharp). The stars are too pixely. Try a blur when creating them. Lens flare needs to go. Not bad.
Errr you need to: 1. Remember compisition. In order for a piece to be amazing it need to have flow and order 2. Nebulas don't apear in the shadow of a planet 3. Work on the color flow Green with gray planets does not really go together 4. Work on the nebulas/space dust Great start
