I strongly believe the amount of blood is not the issue This was after 1! shot with the shotgun!
The activation of blood (as mentioned earlier) and the looks of bloodpools and splatter (texture and shape) is just weird and in this case its even too much, after only one shot.
Also notice how the body has no wounds. It just looks wrong. Thats why they should tweak / improve the gore in the game.
Regarding bullet impact
The drops are barely visible due to colour and shape. Even in lid areas.
Bottom line, Hitman has gore, its there no doubt, its just not polished enough and needs rework.
