Wow. For ghetto setup, that's got some awesome mood and setting to it!
Might be just me, but the focus seems a tad soft. Make sure you're focusing where you want; if this is a self-portrait, as soon as you find focus, switch the lens to MF so it doesn't move. Otherwise, if this is a kit lens, and the kit UV filter is on there, take it off. I've had some shots go soft with that on there, as have others.
