I just uploaded paint charts in 1/48 (@150 dpi).

I spent a lot of time researching the camo schemes and documented them to the best of my ability.
It frustrates me when I see kits that include multiple decal options but only show one camo scheme, especially on a plane where there is so much variation.
There are also a bunch of small details that differ from one plane to another. L
