This is my final take on the Otyugh Trough.
I like this version the best. I've totally lost the contemporary "over-Photoshopped" look, accentuated the hand drawn nature, and simplified visual interpretation. The muck is easy to see, there are no grid lines where you don't need them, etc. At this point I am done with this subject, but I will continue to experiment with this style.
