http://audiomad.deviantart.com/gallery/ would love to know what you think. I think I might be getting the hand of Photoshop I've only been using it for a few months.
Personally, I don't like the word based ones, but the others are good. If I were you, I'd look into more visually appealing areas - that's not to say what you have produced is bad, in fact it's 4 star, but it has a certain cap on 'would I put it on my wall?' because of the subject. I think 'Broken Down' and the Fantasy ones have more mainstream support, or you could go more niche, but that's more all-or-nothing.
Some of those are quite good and really appeal to my darker side. You are really getting the hand of layering and textures and if you keep going at that rate imagine what you could be producing in a years time. Great work
