Scraggy, if you're going to do polygonal modelling just use your intuition, it's not hard at all. My method means getting a cube, extruding faces to make one side of a shirt, then delete the side then use the split poly tool to get more resolution into the charachters, and drag them points out to where you want. Just pretend you're working with clay, first you make basic shape, then define. Then work on the legs in the same way, then on the arms, then the head. Try looking at Kurt's low poly bloke and try copy exactly what he did, just by looking at the lines and such. You will then be able to do it. The project i started is only my 3rd ever model. Polygon based stuff is so easy, just use your intuition and brains of how things should look and you'll do fine
