Oh, I've been hanging around Missing-Lynx for a while ... I just don't post much here.
The winner was very happy, but he might just have been being kind. He builds much better models than I do.
I really wasn't sure of the best way to approach painting the tracks, and I understand your comment of "too much rust". Something for me to work on in future builds.
I consider myself "scale neutral". I'm happy to approach a kit in any scale. My only concern is that, lacking an airbrush, I'm not wild about the idea of painting large kits by brush. This Firefly was almost bigger than I felt comfortable with. In the near future I do expect to be able to use an airbrush (my current living arrangements make using one here impossible) and that will all change, in the meantime I make myself happy with building 72nd/76th kits. But this 48th scale kit was a nice compromise and I expect to do more in future.
