Artist Reply: sort of, its my first atempt at useing HDRI, or mental ray at all, so i was concentraiting more on the render then the model (hence the angularity) but i didnt use a hdri specificly, though i have HDRI Shop, i just used a regular photograph and but a fisheye distortion on it in PSP and aplied it as "imaged based lighting" which seems to work pretty well.
