Jerry,
I really like your all yellow Nashorn. It is extremely vibrant and lively! The weathering and chipping is tasteful as well.
While you didn't post this in the constructive criticism area, I do have a comment. Did you apply the decals on a glossy surface? From the appearance of the decals, it looks like this was the reason you had some silvering. If you wanted, you might be able to lift the decals, gloss the area, apply new decals, re-flat the surface, and weather to your taste.
Again, don't take my comment the wrong way. I think this is an outstanding model, just a note for the future AFV's leaving the Jackson Factory.
