Since the front part of the body is really taking shape now I've started thinking about the tailbox. Initially it was to completly cover the rear wheel which meant an access door would have been needed to make tire pressure checks easier. But this morning I saw pictures of a velomobile called an Orca. It's tailbox has a line starting behind the seat and angling upwards towards the back that leaves the rear axle and some of the wheel exposed. That style appeals to me, it would lower a bit of available cargo space compared to a complete cover but that's okay.
