Hard to find free artwork

Okay, so I'm currently working on a new story that is a tribute to the Snowdrop video on youtube. I'm almost done with it, but I'm having trouble with the artwork I want for the cover.

Namely, I have none. I'm not slouch when it comes to art, but my talent lies in reproduction, not originality. So, I'm looking to see if anyone can draw me up a picture for the cover. I'd commission an artist, but I'm broke as hell right now.

If anyone can spare some time for it, I'd love to hear from you.
