The Power of Pink Precoat

I’ve seen it before in the sub, but to really drive it home, here’s a little before/after of an F-16 tail I’m doing in yellow. Grey primer base, black preshade, pink undercoat, yellow topcoat. I probably should’ve covered more of the preshade with the pink. It’s really hard to get the yellow to cover up the dark areas of the preshade that are too stark. Critiques welcome
