Pictures that give a real sense of what you look like are what I'm looking for.  Too much gauzy light, filtering, retouching, etc. and I assume the provider is covering up some issues. At least a couple of lingerie shots are nice.  

Whether you hide your face is up to you but FWIW, I very much prefer the face to be hidden by hair, lighting, or just the way the shot is framed over a big blurry oval applied later.  Dunno if others feel this way but I'm guessing many do.

Everybody's different re: outdoors, indoors, props, etc.  I'd go with what makes you comfortable.

Your website is fine.  A variety of pics is nice, some sexy ones without getting very explicit are fine.  As previously mentioned, go with what you are comfortable with.  Suggest you smile a little bit more, you look too serious in most of the pics.

necessary to plan a date with you is easily available. I have only two suggestions--(1) remove your phone number unless you like to get calls at all hours of the day or night. I realize you can turn the phone off but you will still have voicemails to deal with when the phone is turned back on.
(2) Change "Pricing" to something milder like "Donation" or "Gratuity". A hobbyist isn't buying a car but rather your time.
