Here is a shot of the child's face UV mapped in maya. What I did for this was fairly straight forward, automatic map half the face, and planar map certain sections, which I could easily stitch together efficiently. This has become my preferred method of unwrapping (utilising the different projection methods together). I used to exclusively use automatic mapping, which was quite stupid as the amount of pieces generated can sometimes be extreme. So what I always tend to do now through practice is to automatic map the model, then break down sections with planar mapping for example. I find it to be a great workflow and saves alot of time.
I did this map as fast as I could as always. My goal with uv mapping is to get through it as fast as possible whilst maintaining a high standard of quality. While I do enjoy it, I also get bored sometimes as it is not the most artistic part of 3D. None the less, it usually is fun, the key is to treat it like a big puzzle.
