I finished this baby a few nights ago, but I only saw daylight in which to photograph her this morning. I'm very happy with how she's turned out - mostly for the reasons given here. Here she is - notes below:
I'm very happy with the way my first attempt at shading fabric turned out, and I'm pleased with some of the modelled details (the gas can on the spare wheel; the winch and the turret and gun shield). Also, although it doesn't show in these photos at all, I spent quite a lot of time on the rusty wheel rims and weathering (specifically, fine brown and grey dust sprayed from the wheels).
Thanks to so much great advice (from the likes of The Antipope at 122nd Cadian and Rasmus over at The Deathworlders - both excellent blogs) I tried out lots of other details too, like rust-style weathering from rivets and some chips from the paint: thanks, chaps - I'm really pleased with how it turned out (although you can't see it all here, alas).
Only problem? The final wash went a bit swirly and mottled. It looks a bit pants at first, but I've come to the conclusion that it's just where the crew tied to swab her down quickly...though why they'd want to is anyone's guess!
Thanks for looking...
