I like the last one.
The rest are badly done, and actually quite auful. All these people who are pussy footing around and just herding like sheep once again, get your own brains.
All it is is a colour with some very simple filters, no real attraction within them, try adding a splash of brushes, be spontaneous. Your latest one is ALOT better and so what if it's tutorialised, you're a learner. Not that I ever used them, don't get too much into tutorials as they tend to pretty much determine your style from then on.
Try and just download a few brushes and get messing around in photoshop, you'll soon get better.
Don't listen to many peoples critiscm on here, it tends to be bad..
Listen to people like TX, Beard, JealY, StoneHelm(when he posts) they know what they're talking about.
