Sorry but there's a whole lot of room for improvements for this wallie.
Before saying all that, I would like you to at least contact the person who made the vector and ask his/her permission first before submitting. I'm not even sure if what you're doing right now is not against the rules of MT. After, please credit him/her in the description.
The extraction of the vector is worse than desired. There are actually lots of white or blue "leftovers" in your extraction. Graphics and idea makes this wall decent at best. I hope that you'll learn a lot with this wallie... It's certainly what counts in wallpaper making. :D
Edit: Oh and I like the seal and the fire thingy too.
