Nice! Where did you find the patch? I didn't see it on these forums - should I be watching TtC's picture account?
Also, although the physical parts are nice, the RCS thrusters (or whatever those red squares are) look weird to me. I can't find any good screenshots from the actual episode that show that area with good quality, and the other vaguely official versions (models or computer images from official sources) have conflicting views on whether they're supposed to look like that or the solid yellow like on the D.
