Would rather have a few decent pictures of face, body, underwear etc showing the true picture of the girl. Nothing worse then 100+ pictures of just a close up of breasts/pussy, lying of bed sucking cock and all that. Even worse when you have paid a few credits to see their private gallery only to find 200+ pointless pictures.
I also understand why some girl hide their face but its a fairly important part they are hiding. Whatever body type / size you like if its got a dog ugly face it going to make a difference if you book or not.
Once you have the basics right the girl has a fairly free reign how she poses. On a bed, stool, table, kitchen hardly matters to me as long as you get a true sense of what she is about.
