Nice job with the extraction of source1 and the creation of the background. I think the flames could use more attention. Perhaps some more contrast on them, they seem a bit soft. Good luck!

Well constructed, but I don't get the water background...UFO parts the Red Sea?

its not in the red sea, somewhere in the ocean UFO hide. LOL

Author, your flames were made in the wrong way. Just remember images like this one http://www.deviantart.com/download/106640611/The_Flame_by_AuTuMn_Lee.jpg
Normally, the fire is brighter close to the source of the fire where the heat is maximum. So, from the center, the order of colors should be white --> yellow --> red. Sometimes you see the blue colors, it means something was burned more efficient, so more heat is released (more than white fire).
Hope that this helps and good luck with the contest!
EDIT: Yes, at least it's correct now!

(Fire) fixed
thanks to you langstrum

It's great that you fixed it author, and nice idea with those waves. It might not make sense for some, but it works compositionally and it's pretty original!

Btw, you should thumb up Langstrum for taking the time to help you, he deserves that much . ( it's the yellow hand at the right of the comment section- click on it).
Good luck.

wow! complex... suggest the lower part of the UFO to be much smaller

Very creative, love it
