Hard to pick a favorite, but this Space Carrier caught my eye.
I especially like the all black background. Is it real or is it photoshop?
UPDATE: Pasukaru (whose real name is Pascal Schmidt) posted this description of his photo technique:
I shoot stuff like this by using a black T-shirt for background. Normally I just adjust the black point of the image so that the background really becomes true black. For this one I used a different approach, selecting the whole background (fuzzy select in GIMP with some minor manual adjustments and a 3 pixel feathered selection border) and then filling it with black. Works well if there is enough contrast between the model and the background.
