I see where people are coming from with the hentai-esque vibe - after all, much of it follows a story of a purely white, entirely naked woman and a hulking, dark, seemingly masculine man-beast. However, upon closer inspection, I noticed that the troll has no genitals and really is hardly humanoid at all, minus the basic figure. In the end, I feel, based on the woman's visage (she could be a girl, the smoothness of her chin's curvature would suggest that) that she has a confident bond with the troll. It's as if you are right there in the woods, coming across this woman, and she smiles slyly because she knows you will never come near her as her giant guardian comes out of the shadows, like she's the queen of the forest, and in turn of the troll, or something of the like. If the troll were out to attack the woman, at that distance and with his length, surely his arm would be raised in preparation for a strike. Instead, the troll is pacing forward calmly, further implying both that it has a bond with the queen and the intelligence to recognize said bond. As for it's face, I see how people would think it's slobbering over this naked woman, but I think the troll's face just looks like that. If we could see the troll moving, I feel like its jaw would just dangle and swing side to side powerlessly, which would mean that its potential intelligence lies on the inside. Overall, this is the stuff of fantastic imaginations, I really enjoy it :3
