I feel you with the art thing! Library references are awesome but I also wanted to suggest this to you:

Posemanaics has been a huge godsend to me, especially the hand viewer. If you click on any of those poses you can add grids, drag them around, etc. It's super helpful! It also shows the muscular systems, which is nice.

My primary interest as a creator is also in horror media, so I'd love to see anything you guys make!
