Thanks tweetytunes and good luck to you too!

Here is a more defined look after about three hours of modeling. The baseline hull and canopy area are defined although I'm not too happy with the foward arrow scoop. The basic idea is that there will be a secondary layer of panelling to give it further shape and break up the smoothness of the racer without losing too much of its aerodynamic profile. The hollow in the front is for the bit of the engine/internals that will be visible.
