Can't compare Ivana to Cameron, Tarah, Little C, Paige, Alexis, etc...... They're all different in their own way. Yes, I saw them all multiple times (except Paige = once).
My impression of Ivana was she was one of the most naturally beautiful women out there but didn't like the bullsh#t that some customers would bring to a session. I never had a bad session with her but never really clicked either. The times I saw her were at the end of a shift so no telling how many jerks pissed her off that day before I saw her. I don't think she was the type to put up with any crap either and would tell a client just so.
