I'd say his work is mostly just okay. Way too often the lighting is bad and the camera angles are even worse. What do you want to see when you're watching porn? Softcore porn angles, lots of bouncing balls or actual penetration? Because the penetration is rarely really shown.
Well, we have entered the realm of opinions, but since you asked I'm part of the people that are not fan of zooming on the actual penetration. Genitals penetrating genitals doesn't do much for me. I much prefer the "shape" of people making love, I much prefer the positions from some distance.
And yep, lots of bouncing things, the more weight and momentum the better, up to a certain point.
From HunicornD specifically, I loved the perils that he used to put their characters into, like Tryndasam mentioned above.
Triss and Yen turning into stone statue, or getting stuck in a painting, Samus getting infected by a symbiote or impregnated by an alien. That sort of bad ending without guro used to add context and consequence to the action.
So even if the action itself is not the best, the fact that it's decisive to the character's fate and potentially the last thing for them adds weight to the scene.
