Trym, first, welcome to NPN and thanks for posting. While Iām having a hard time seeing trolls, I am enjoying how much the right 2/3rds looks like rows of nasty teeth. You could enhance that by cropping to 8.5 x 11, removing the flat part in the upper left.
Hi Trym, wow, this reminds me of a similar image I took of icicles which looked like teeth. B&W makes it even more scary and ominous. I do like the curving horizontal lines crossing the image, as well as the bottom where the snow seems to be flowing down. Can slightly detect some dark troll images in the lower part, one with his mouth open.
