Actually to be honest i didn't have much of a choice for the image. I ask a friend of mine at my work to take a picture of his desk for me to put some 3d object in it and he give me these one and since I don't have digital camera and I know how busy he is I had to stick with what I have. And the angle that you where talking about the x and z are perfectly aligned maybe Y is the one that looks wrong to you I don't know looks ok to me . Cheers.
