Looks fantastic-I really love the weathering. I wish I had the skills to do that sort of thing for myself.
Just a couple of notes-there's a great deal of evidence to suggest that the monitors were painted light gray during the war. This hypothesis does make sense, since black or dark gray would make the already cramped interiors quite stifling.
Before I go any further, I will say that the darker color is more aesthetically pleasing so if that's why your doing it I do apologize.
Another point of interest is the turret roof-yours looks really nice, but alas I have to say that this is the one ship where I DO know what the turret roof looked like
Again, if this is purely an aesthetic decision, please forgive me...
In any case, it is looking excellent, your doing a very fine job, and I do *like* the improvements.
