Colour management + chair

Damn colour management. Both of my computers are set to have the proper colour settings, but when I transfer the images across...it goes BLACK... Anyhoo, I rendered my chair-room thing so far (basic chair, not the real thing)... This is it at its most basic... like seriously basic.



I really have to fix this colour problem... I had to adjust the levels in photoshop...EXTRA BLOODY WORK. gay.

Anyway, please add comments on how I can improve. It'll look very different when completed, but I just thought I would quickly chuck something up. Whatever you suggest I am probably in the process of doing anyway, but it'd be good to get some kind of feedback, if any.
