I've got this far with the "generic long coat" model (this variation being a "western-style duster jacket"), but need some hints / tips / thoughts / suggesitons on where to go to from here. The model itself isn't a great deal different from the NCR troop's long coat.
Generic long coat (with optional "Cowboy hat", for those which are into that sort of thing).
Hat can obviously be separated, but I'm sure you can make him bald in your imagination for this picture :-)
I'd done a couple of tests with colours and alterations, and it should also work in black, grey, light brown, and with minimal changes, an "olive military trenchcoat" as well.
It's noticeable from the little "approximate game size" version in the corner, that the little pockets are probably not going to be visible at game resolution, so will at least need another round of increasing highlight / shadows etc. I've not done much with the shirt / trousers so far, other than a quick recolour and adding a belt. Also not sure if the overall brown colour is too "rich" in tone, and looks too clean / new etc.
Anyway, it doesn't look finished to me, but I could do with some suggestions about what needs doing to it from here. I'm particularly wary of it looking too much "Wild West" and not enough "Fallout".
