I'm not convinced that this is possible. That is, I'm not convinced that there's a way to create a 3D model of a human that doesn't look completely creepy. I'm trouble thinking of even a single 3D game or movie with human characters that didn't creep me out at least a little bit.
Anyway, there are a ton of learning resources available. If you can't find anything for free on youtube, you can look at paid content on udemy.com (but wait for a sale, because courses priced over $100 regularly go on sale for less than $15). But even with those resources, this is a hard problem.
