Thanks for all your kind words. Indeed I do this for a living, although I spend 1000% more time in it than paid for. Just because it's addictive and so much fun. But I am able to work in TG2 most of the day, and indeed some works need all that time to put together (including making all the objects, which I only started to do a couple of months ago, so I'm not fast and efficient) and test until every bit is good enough. I know I can make the images more realistic, but there's a saying; put 50% of your time into a product that's 90% right, don't waste another 50% on only 10% better. Not always true, I know, but commercially it is.
Anyway, I will post a changed POV, rendering now at different settings. I already see that 0.85 and AA6 is quite a lot better...
The mud is a painted gray mask (1000x1000px) in PS, using textured brushes, with added (warped) fractals in TG2. The thing I mostly regret is that I cannot get rid of the white artifacts where reflective transparent water hits reflective mud. I can, but only if I make the water far less transparent, or use Ray traced reflections, and they are not perfect either. If time permits, I'll dive into that. Mud is great indeed.
