Siren Head Character

Hi all. I've decided to try making a character scene. I've got interested in Siren Head creepypasta, and all that thing. Followed tutorial by Ian Hubert on making moths in scene, and try it myself. Also followed tutorial by CG Matter on making clouds, and added them as a mist. Mesh is a total disaster and only couple things looks a bit good. All textures downloaded from HDRI heaven.
