What a paint job. So much depth. This is very close to what I consider to be an idea single-color paint job. Don't know if it's the most realistic (maybe, maybe not), but it's certainly the most fun to look at and most suggestive of size/weight. Very cool.
One comment, and I'm loathe to make it because it's probably a photographic artifact: the tarp roll on the sponson seems to be just a touch glossy. I think it should be dead flat (although maybe it was impregnated with something that might give a slight sheen). I'm sure a quick hit with some PollyS Flat or Testors Dullcote, or even some tan pastels, would kill the shine in a second.
Again, I really like that model.
