IRay test render 2

So this is my second published Iray test render. Much better than the first one

2 curved mesh lights, 1 photometric spot as rim light, no environment map on the dome.
2h render time: (GeForce GTX 560 Ti): 2578 iterations, 19.159s init
Postwork in Photoshop, similar to my other renders.

Again the metal/reflections look a lot better like anything I ever managed to get from 3Delight.
Skin does look a lot better in this one compared to the first render. I tweaked the skin shader a bit. Don't like the IRay skin shader for Gen2. For such dark skin it does not look too bad.
Feel free to compare with this render of the same girl done with 3Delight:

Main problem is still that I have to relearn everything from scratch. Completely different lighting and shader settings compared to 3Delight.
Second one looks a lot better than the first. Still don't know if I like it better than the 3Delight render though. let me know what you think.

I probably need a new nvidia card to have fun with Iray. With my old 560ti it is still far too slow for my liking.

If you want to know anything, just ask.

Edit: Since this are the first steps with the new render engine IRay, I would very much appreciate your comments on what you like or dislike in this render. Also compared to my other 3Delight renders. That would really help. Thank you all
