One of my favorites you have ever posted!! WOW! Great realistic render too. Everyone always brags on the big name render engines out there like luxrender, and octane, cycles, and such. But much of the best renders I've ever seen by the pros were done with that mental ray. I tried it once when I had the 3dsmax trial installed, but I couldn't get anything good from it because it was so complicated to me. I give you incredible respect for producing such high quality results from a really high level render engine like mental ray!
thanks for your comments.. ive just grown comfortable with mental ray over the years and ive banged my head on my desk several times trying to get vray to get near this sort of quality with really bad results.. iver never really tried anything else much.. im no good working in blender but i have to admit that the new cycles engine does some fantastic work pretty quickly.. ive seen some mind blowing renders done with it out there and i jut drool sometimes
