Color. Oh color.

Finished this today.

I can't take full credit on it though, because I did study off of another piece.  In my attempt to dive more into the wonderful world of color, I stumbled upon this:

This is "Nebula" by Dave Rapoza.  He also has a plethora of other awesome covers like this, as well as an impressive gallery that can be found on his deviantart and his blog (http://davidrapozaart.deviantart.com/art/Nebula-396430191)

I shamelessly decided to browse through his works and imitate his color choices.  While it's not to his caliber, it did help me with some interesting color choices.  Still learning.
