I like the way you've done all three and, although I can't comment on the design (it would be cheating) I'll give you a few pointers. First of all, if you are going to do the front, spine and back of the cover try to make sure they are all in proportion and would fit together in terms of colour schemes. Another thing; you have a tiny typo on the spine where you have written 'IcyFlames' instead of 'IcyFlame'. Thanks for entering!
The cover looks like two forces of epic proportion are colliding and doing battle in the sky. I don't know what IcyFlame's novel is about, but I hope it's something like that. Iceflame was right though. The three pieces of art should all fit together. It's a little wierd to pick up a book and have it be three different colors. I also like the spine, it looks like a bunch of clouds/the sky. The back... I think the quality (as in pixels and what not), could use an upgrade. The words seem a little blurry to my eyes.
A suggestion from me would be to put all three side by side so that the people can see it easier and actually picture it as a cover. If you did this in a rush, I would love to see what you would do if you took your time.
If words are just letters put together, why do we decide on what they mean?
I like the front cover, minus the font you used. It's a big of an obnoxious font, and the title hardly fits on the page. I would suggest something more subtle, and perhaps the colour white? I like the spine, but it does not match with the front cover, and neither does your back cover. A book cover is not 3 separate pieces like you've shown here, it's one. The front cover should flow into the back cover with grace.

*edit* This is a lot better! The covers are in proportion and the font really fits well. I'm not so fond of the picture on the back, you can't really see the writing. Good edit though!!
