After finishing the initial version of this image, I wanted to get a framed print of it. But I quickly realized that there were some things that hadn't turned out the way I wanted the first time around. Hence, for this version I did quite a few revisions before rendering it in big scale and I think it came out much better.
The poster size is 100x50cm (~39"x19.5"). That translates to is 11811x5906 pixels, in order to get a 300dpi print. The render I've uploaded here isn't in the exact same aspect ratio, but fit to 16:9.
