Very unique and I think it makes it even sexier that Asami and Takaba are out just out of focus enough that you can't be 100% sure what they are doing, but you still know it's the start of what will be a sexual encounter. I think the costumes and players are perfect for the characters they are to represent. Even putting Asami on top is exactly what you would expect if viewing a page from the manga.
The gun though, that really just makes this perfect. Violence and guns are such a strong part of the series and really do go hand in hand with the sex. Putting them together like this captures that without requiring a depiction of either violence or sex. I think by making the gun the in focus foreground item with the characters the out of focus background is spot on for everything that Finder is.
Job very well done. My only complaint is that I wish you had more to share as you obviously understand the series and have a mastery of photography with which to show it.
