@Drkmttr2007. I do have sets, but would you mean sets for RMXP character sprites ?
Here's a collection of portraits from 66rpg, quite a mix with around 60 in all. In the
illustration Iv'e put Tay Du, an old chinese online game which I believe they come from.
For RM purposes, they just need cropping to square them up.
