Three words is what I would bring and that is variety, variety and variety!
More variety of storylines.
More variety of female performers (not all slender teen looking models, not all lesser known newbies, let’s have some more established stars too).
More varied levels of hardcore scenes (some vanilla and intimate. some rougher, some anal etc.)
More variety of male performers (John Strong, for example, seems to be in a lot of scenes unless I am mistaken and, based on what I’ve seen of him, he appears to be very short which doesn’t work great for some positions, especially with taller girls).
Focus on the art of making the scenes look great, getting girls into great positions, good lighting and clear views of penetration instead of efficiency (i.e. let’s see how many positions we can tick off without moving the camera around).
Just a few thoughts.
