um good question i know their is a way to add pictures for the faces to it. and for sprites a sprite generator perhaps? for the pictures for the face take ulrika's face and use a picture editing program called paint.net so you can save it as a png format.
go here and it has the programs used to make the faces pictures

oh if you want more stuff to put into designs for cities or dungeons ill look for them some with some sprite generators.
