Use finely stranded wire so you can get nice contours and bends. In particular, I've always thought that the 6 gauge wire provided in the kit is absolutely aweful because it is not finely stranded at all and is very stiff. Spend the money to get some nicer wire (less resistance too)

Also, those sticky backed zip tie "mounts" will come in handy for securing wires.

Last, wire wrap of some sort often (available at auto parts store or maybe hardware store) does a nice job of tidying up things and works great in a situation like a flexible joint of an arm. The stuff is black plastic tube with a slit down one side.
