I won't pretend mine are up to the level of some of the above, but I would like to start seeing some of y'alls' Dark Avatar designs, so I'll start with some of mine. I made these during the beta, but the templates still hold up in the finished product. They are all Terran style ships, though I started all but the Transport with the little cube hull and worked from there. The bronze/brass color scheme reminds me of a cross between Flash Gordon and the Guild ships from the Dune movie, and I've been using it for some time now.

Fighter (tiny hull):
