I like it. I've never made a texture before creating the mesh, I just can't plan things to that extent.
One thing I would say is that you should have more detail on the sweet spots on the model, in other words the areas that peoples eyes are drawn to. For instance, the hands should get a decent sized area of UV map because they can be close to the camera. The feet as well should get a little more real estate, because people always look at feet and they tend to be disappointed - when someone puts in a lot of effort on a foot, whether it's an old boot or barefoot, people notice this stuff.
The other areas look good, but I would probably expand to the less planar areas, like the shoulders - I'd keep drawing up until the opposite side of the shoulder was taken care off too - nice and easy to UV map, and again it's an area close to the camera.
Look forward to seeing how it turns out.
