I have done them before, but the ones on all the dolls in my gallery were done by my best friend. She lives all the way up in Winnipeg :<
I'm not horrible at them (I was an art major, after all), but the only doll head I had to practice on I sold a couple months ago so I could buy a Nook Color, lol.
I have a list of a few dolls I would really love to have, but I've sort of slipped out of the hobby since I have so little spare cash and actually have to spend it on adult things now, lol. If I ever ended up with a random $500 I'd love to finish my WS LTF Ante Elf faun. I've got the hooves for her and I just can't bring myself to sell them in case I end up with the money to buy the doll!
