I thought about slapping on the logo but I was in a hurry when I did it. I tried to model the apple from memory and apparently I don't remember what apples look like exactly,
The hand model is actually a model included with Poser so I can't take any credit for modeling it.
The most I've done for computer games is designing levels for Quake 3, Urban Terror and Unreal Tournament. It is big time work since in FPS the entire "set" has to be tight and allow proper movement unlike these renderings which use alot of illusion to make things look more "complete" then they really are. For instance in the 2nd image the room beyond the door and the other through the window are really only a single 10' wall section and a single 10'x10' floor section since that is all you can see from the finished camera angle.
