Thanks! In person you can see the lines a lot better as most of them are "drawn" out of metal rods like so:
Right now I'm just doing finishing work which isn't terribly hard but it is time consuming.
I didn't actually draw the blue render - I've got a kid working with/for me who does all the concept and artwork stuff as I can't draw for crap. I'm pretty sure that's Adobe Illustrator he used to make that one.
