Manga artist needed to create portraits for a dnd game

I am looking to have 5 pieces done. A portrait of each of my 4 player characters and one of all four of them. They picked portriats already, three of them they made using a character making program and one is a raw image. I am hoping to stick with the visions they had but they are just head shots. So the rest is up to you. I can provide further details if needed. i.e. class, weapon, what they might be wearing.
