Well off the top of my head the Ki-44, J1N1, H6K, G8N, G4M, Lavochkins ( i think darthpanda started on these though), LaGG, FW200 (sources are somewhat difficult to find), Ju 287, Typhoons, some temptest variants, and numerous variants of the already drawn FW190, Bf109, Bf110, Ju 88, Ju 87, and He 111's are still left to do
I have stuff for all but the h6k if you wanna try to draw something.
