Sad to say I am getting the generic vibe strongly off this cover. As much as I like the sword in fire image, the cover feels like it needs more meat. The title probably doesn't help in that regard, as they're kind of feeding off each other. Except for the blue stripe, this feels like something I'd see in a portfolio of premades. You probably have strong reasons for choosing the title, but the rest can be changed.
The only issue I really have with the sword and flame is that it's one-note. I'm no artist but it feels incomplete. If you could have something backgroundy behind or around it, perhaps a landscape or city or the interior of a house, that might help. Most of the artists I've seen who use stock photos always use three or four images and composite them, but this is like a single piece of stock. That's what stands out most to me.
I'd lose the blue stripe. It's clashing too much with the rest of the cover.
One thing I've noticed about a lot of indie covers is the author's name being prominently at the top. As a rule I think this is backwards: Big publishers do this for their A-listers because it garners more attention, but for most books the title needs to be more prominent. I think it's better, usually, to put the title at the top. The series can go either below the title or below the author, whichever works best.
By this same logic, the title needs to be bigger than your name. Ordinarily I'd also say the title needs the splashier font, but I very much like the font you used for your name.
Finally, the font you're using for the title and the series isn't working. It's too thin, and has a typewriter quality in the uniformity of the letters. (The descending style of the W is nice, though.) The weathered look doesn't do any good to the typeface, and it's also hurting the way the series name looks at a smaller size. Just doing a quick glance over at FontSquirrel
, I see better choices among Artifika and Caudex; there may be other good ones, especially if you use a small-caps approach so your lead letter is always slightly bigger. Make the title thick and readable, and it will handle the transition to a thumbnail size better while also doing more to catch the reader's attention. If you do this for the title, make it bigger and move it up, then nestle in the series name below it, I think you'll end up with a much better look as far as the text is concerned.
