To be honest, I'm incredibly pleased with the result. I spent half a day with the overall structure, and in general learning how to blender, and another half with actual sculpting. I made many mistakes and had to go back. I even messed-up in the end. This is too heavy I believe, and the topology is terrible because I wasn't constantly re-meshing (I wasn't paying much attention to the tutorial)
Can’t wait to learn Substance 3D it looks so cool for texture painting
