I'm working through learning how to sculpt in Blender. I've found that MarshmammL on Youtube has a really good tutorial for beginning character sculpting. https://www.youtube.com/watch?v=KsDe1V9Dl-0&t=364s I second the Flipped Normals. I've been watching quite a few of their videos lately. Plus, they have a Basic sculpting class on their website that isn't program specific.
