Here are 3 different skins for the Su-33 in form of fictional Chinese J-15 paint schemes.
These are mostly made up but still slightly based on real aircraft.
J-15 Shenyang - Flanker-X2 - Chinese Air Force
I use Deka Ironworks textures for engine parts, text/stencils and the chinese pilot.
Included are RoughMet files, optimized for the Shenyang liveries, based on watermanpc's work.
Here are some screenshots of the new variants. They come in White, Dark and Blue paint schemes.
