Have you started incorporating the POV style into your castings? I have noticed on recent castings that you are holding the camera during the session. What is happening? Only on rare occasions (in my view) does certain shots in POV work. The main problem is the inconsistency of the shot because it isn't steady and often jerks. No I am not a fan. I hope you don't start going down this route.
Your usual method has been tried and tested over the years however, it could be improved maybe if your looking to evolve and change the look positively.
The camera you use these days is superb quality so no change there needed. Its so subjective I suppose when it comes to angles. You usually put it on a table etc facing the bed in a static position which in general has been great few the years. If anything was to change maybe a little bit closer if possible.
Me personally I like the missionary position where you can see the girls face in between her legs under you balls

Keep up the good work and please please if there is any way i can come and work for you let me know
