Today I decided to dedicate my time to texturing, because the possibility of not being able to do anything with this model that I've been working on for so long was driving me crazy.
So, I took the head and searched up some tutorials on UV unwrapping and baking (which for the time being, I only know how to do in Blender's internal render, which I don't work with very often), and I got to work.
Here is the baked UV map, which I rendered with plain colours from Blender's internal render. So, basically just a rendered version of the WIP pictures I've shown throughout the modelling process.
And this is the vertex map. I didn't really need this, but I decided to have it anyway because it would help me determine which parts of the model would be visible while I was painting it.
And here is the finished UV map. As it was a test, I didn't add any fancy details to it like I intend to at a later time, but I enhanced the glossiness and I did some colour correction and brightness/contrast adjusting.
And this is the finished result! With no lighting set, so you can see how the texture looks on its own.
