My Try at a Cover for Moody Fantasy Epic

Here's what I came up with, limited resources that I have, for the first volume of the epic fantasy I'm working on. It's somewhat of a dark story. Does it work to convey a moody, fantasy feel? Even vaguely? I know, I know; I need an oil painting of a solemn group of adventurers against towering mountains and stuff, but I don't have the time and resources for that unfortunately.

I'm posting the full image and a thumbnail. Is the smaller readable? Is the larger interesting enough or that it might catch the right audience's attention? Does the composition work?

It sure is tough doing this all on your own, I'm finding.

Thanks everyone for your input! I really appreciate it.

I can see what you are saying to some degree Gale. Unfortunately, I don't have the means to invest in a professional. It would be great if I could. But I'm hoping, at the least, the vector/ angular art conveys something about the mathematical/ geometrical (hence, "Omnigon") nature of magic in my world. I've had some good criticism and suggestions since publishing, unexpected admittedly, and I'm revising my files based on it. I figure it's a late last chance to improve, so no worries about what it's been incorporated into.

Thank you W.S. and Williebee for your comments. I'm glad some things about the cover might be working. The book does have some science fiction-like qualities to it, interestingly. No young, upbeat heroes though--just an old, angry, disturbed wizard. Hmm, something else for me to think about here.

merrihiatt, thanks for offering a comment. The book actually does have a kind of religion-themed conflict, and I was definitely hoping to suggest a biblical quality to the image. Hopefully I didn't go overboard, but I'm glad to see it's apparent.

Good observation about the focal point, though.

Again, thanks, everyone for the input so far.
