My best piece of creative work: "Apocalypse"

This was an image manipulation I did a few months ago while playing around with the program GIMP, a program very similar to Photoshop. I started with an initial image of a desert, then added the explosions/fireballs, the woman in the foreground, and changed the lighting and colours. It's pretty amateur I know but hey, I'm not that good! I don't really know what I was trying to convey through creating an image of a nuclear-type apocalypse, I just thought it looked cool...
