I recently started out playing with KRay... and I thought I'd post a small example of the experimenting I have been doing.

I used a lot of the tips and advice posted on this board...
It is only a low-res render; the resolution it has to be deliverd in is 1280 x 720 as animation (walkthrough). Also, I kept the AA settings low to decrease rendertime.
In photoshop, I applied some color correction (mainly contrast) and some sharpening.
I would really appreciate suggestions or comments!
Thanks
