V nice mate.
The problem I find with the O/D is that there are so many differaqnt shades it could be, depending on amount of sunlight/heat, dirt/dust, age etc, so none are incorrect, none are right, just an individual preferance.
I sorta like the brownish tones - I've tried getting it just right on B-25's so often that I had to put it aside or commit violence, but I did manage to get it where I liked it on a batch of P-40's once. Difference in scale effect maybe?
I know it makes a difference on ship models - smaller=more distance=lighter if you want to replicate what a full-size ship would look like from a distance that replicated the apparent size of the model.
I like the brown shades too but I also like the faded DO best
The DO on the P-40s looks pretty good but if I had to guess I'd say it was fairly new fresh paint
Looks good, very strong details but still subtle, nice balance!
