I would crop out all of the useless details, like the orange streaks on the right, the highlight at the top, and the void at the bottom. Then I would give it a bit more exposure. Dark and moody is cool, but underexposed is not. There is a fine line I think. We need to see what's going on at least a bit.
I second what Matt said. I would also straighten up the image a little. In art it is is not perfectly straight then it needs to be real crooked. It is messing with me that the image is a little crooked, but sometimes it is fun to mess with people. I do like the dark effect with the shaving cream, but as Matt said it might be a little too dark. Keep it up.
What exactly do you mean by highlight and void? I used the exposure on Lightroom but it only messes up the picture. Also vignetting in Lightroom is what i used to make the angles darker.
There go another one..different pic btw.
This one has more color in it..kinda wanted a little more red/brown innit but i still couldnt get it right because i didnt want it this dark but if -once again- i use exposure, it kinda messes the thing up.
