Arms and legs! It took me ages to figure out how to fill the gaps in the mesh as there was no mention of this on my shortcuts sheet!
I started having a look around the Blender tools trying to figure out how to make the model look smoother. After many frustrating bashes of ctrl+z when things went crazy on screen, I finally found the mirror and sub-surface tools. The more I sub-surf, the more surfaces are created, meaning a smooth look is getting there. Annoyingly I didn't find the mirror tool until after I'd created the other half by hand (trying to get them identical was a mission and a half. Never again). I decided I might as well delete the left half and use the mirror to help me on the rest of the modelling.
So far I'm finding this 3D modelling not too bad, though
