Hi i painted this for my son's birthday. I had never heard of Cthulhu so I'm way out on a limb here. It was definitely a different sort of challenge and I guess that's what I love about learning how to paint using the bob ross tutorials. I not only found something to pass the time (im a 2nd time widower)but whether I'm good at it or not I've found something I love to do. I think that Bob Ross would love the fact that his shows are still inspiring people to not only try it but to build up the confidence to try something totally out of their comfort zone such as this was for me. Happy Painting out there!!
