Does my cover look professional?

I'd say so.

I like it very much, though it doesn't tell me exactly what the story is about, so you need a good blurb to back it up.

I think it looks fairly nice, though I'm not sure entirely how it works with the story, so I second what jnfr said.

I like it. Great cover for a fiver!

I would suggest that the title is not going to be clear at thumbnail size, and the illustration is a bit low contrast and ambiguous. (Some kind of wooden chest and some kind of smoke? That could cover a lot of things from a contemporary ghost story or a pirate battle at sea?)

Ooooh, very cool. I like it.

Like someone else said, it doesn't exactly tell me what the book's about.

Somehow I didn't see the dragon until it was pointed out.

To answer your question, no, I don't think so.
It's hard to tell what the image is, and it looks a little too much like someone just slapped a ps filter on top of a mediocre doodle. Which is exactly what you're gonna get for 5$.

To summarize... It looks cheap.

Sorry.

I think it looks good.

I'd ask the guy if he can fine tune it or make a little better one for $50. He obviously has talent.

The three least professional things about it:

1. You're using a low-res image. It's also murky and doesn't say much, but that's something that can happen at any level. Low resolution is something you only see on self-published books.

2. Another thing you don't see on professional covers: no cover copy beyond the title and the author. You only get to do that if you're a household name.

3. Using an all-caps serif text face as display type. It makes it look like something you put together in Microsoft Word. Get rid of it and use a proper display font or two (but not three).

Looks good to me. If I saw that on a shelf I'd definitely give it a look-over.

It looks OK for the size displayed, but I have to wonder what happens to the font and smoke at a lower image setting for say Amazon.

I discovered the smoke was taking on a dragon form almost from the get go, but it made me wonder what a dragon has to do with the title. I might read the blurb just to see how the cover ties in...

I like it. A lot. But, I do agree that there needs to be more contrast and the subtitle A Dark Brigade Tale gets lost when the cover is shown at less than full screen; a thumbnail may look like a muddy brown rectangle. Some fine tuning is in order as previously suggested IMHO.

I guess I was looking it as a reader (since I am one) and not as a graphic designer (since I'm assuredly NOT one). My initial impression was that it looks great and I would pick it up off the shelf, even if I wasn't that sure what the genre would be. The elements of the picture appealed.

Having said that, I think you've gotten some good advice re the sub-title and the all-caps title - from people more aware of these things than I am!

But speaking purely as a shopper, I think it would catch my eye.

interesting cover. Up size and bold out the second line.

Best wishes with this.
