There are a few things I could have done better, and I hope I will in the future.
My value sketch didn't account for OSL enough, and it got completely lost when I layered on steel metallics. I maintained diffuse, zenithal lights and shadows all along, but when it came time to do OSL after having finished all painting and weathering, I found myself layering orange inks over black and that wasn't working out. I went back with a brush and reconstructed some of the OSL values after having painted the rest of the model; that's unfortunate.
The decal on his loin plate is too white. It's no surprise since it's a white decal, but I should tone it down. It's in deep shadow and it should pop out as much. The black side of that decal got ruined when I repainted the beige part of the plate. I may need to go back and reapply the black decals there, humph.
Due to the fact I was doing orange OSL over neutral to cold tinted metallics, there are regions where the light tints green a bit too much. I should have warmed up metallics in vicinity of where light would be, just to be ready for warm colors.
There were a few places where the paint has rubbed off from handling, and you can see them on the pictures. I've touched those up already but I don't want to do another photo session.
All that said, I'm still very proud of what I got here. I definitely stretched my limits here and have learned a lot from it.
Enough words! Thanks for looking.
