Is this based on an H-game of 3 Kingdoms? Name of artist please

Actually, if you asked me, it looks like Dynasty Warriors all sexed up is all.

in fact, there is a h-game based loosely off RTK. released quite recently too.

but this image is not from the game, this whole series of female RTK illustrations is just a fanwork i suspect. :P
