First Attempt at Creating a Cover

My first book (as CJ Zane, anyway) still needs to go through a few more revisions, but I'm thinking ahead to the release, which I'm going to do everything I can to make sure it happens before the end of the year. I would normally buy a pre-made cover, as I find those to be excellent quality, but I thought I might try my hand at creating my own. This is not the final cover, and the final cover most likely will look nothing like this, but I thought I'd share my first attempt, just for fun. What do you think?
