R2 Texturing

Getting to the hard part, UV unwrapping. it is difficult trying to work out if maps should be unwrapped cylindrically, boxed or spherical. So far Ive only been met with disater using cylinder, but box seems to work for everything with the exception of outwardly spherical objects like R2 units head.
Im blogging about this as its the first succesful spherical unwrap I have done. It is very similar to normal box UV wrapping, and it gives a much more curved result. It is, however harder to draw in GIMP to get the dimention of curvature right, but it is definately work it. I am also finding the hide all unselected button very useful at this point. I will also add quickly that I have added just the white texture to the base of the head. I know this is unneccesary and If i wasnt so scared of messing up my model at this point I would delete it. I will note this for future reference.
