Distortion?

I seem to have problem with some height distortion in my 3d model, I hadn't noticed it during any of the previous tutorials, any idea why this might be happening?

I would look at adjusting the perspective distance to the object.
It's distorted because it's to perspective IMHO.
Adjust the distance and you'll look just like the other picture.

Ah yes, I've just adjusted the camera and it looks much more accurate.
