I have learned and created a human model which is near to perfect, at least for me 
now I want to texture the whole body, How should I approach. I have seen this tutorial https://youtu.be/2fcnmyLK-uw on youtube and I feel confident about the face part I do it well but i am wondering about full-body texturing. I have researched the possible ways. There a procedural way of making skin but isn’t realistic much, there a method using nodes and maps, but maps are rare to find. So I have decided to texture paint in a blender by UV unwrapping the whole body then manually painting the texture, but i am sure, with intermediate skill it wont be easy, at least i think so, so please please suggest to some ways tips and tricks to do so. my priority is realastic texture
