I watched a few of the sample videos and some faults are obvious. The music is far too loud, no real sound and above all very little interplay between the people fucking. They're making passionate love together, not two porn actors doing as directed. give them some space and time, then let them get on with it. Two cameras would be better than stopping and starting.
Also cut out shooting with roses in between the camera and the action. It's so old fashioned it was done before my time.
The cuts in the samples are to abrupt, once the viewer gets the hook you let him saviour it for a little longer. Pulling his chain too fast is annoying.
It's great shooting, great definition, setting. Yet it lacks the sharp edge it needs at this level. And I'm not talking about anything technical.
