Look forward to seeing more, it’s really coming together nicely.
So, here it is. I also changed the lightning a little bit to bring some shadows in there.
and gave the dark parts a slight reddish color with the color balance node.
i think the next render will be last for that image 
I’m fully expecting to see this in the top row after you post in finished. Wow. terrific job.
Really nice, I like this one a lot.
I’d love to see a really high resolution version, if your machine is burning up on it feel free to pm a packed blend and I can do an overnight on a 780. Cheers.
Thank you a lot frobenius.edge, I aim for that since I started here, I’d really appreciate that.
thank you photox for the offer. I already got an hardware upgrade, so the render times are much better. (got a 770, and I’m considering buying a second one :D) There will definitly be a bigger version 
So here is the final render in full size.
I experimented a lot with the post processing. And also worked on different angles, but I ran out of time, so I have to close the project now.
thank you for all the help, great community
Good job!!
Really nice sirnik.
As a new guy - I just wanted to chime in and say that you have set the bar quite high for me! I hope to attain this level of realism one day! Great work!
