Not an uncommon situation...
Sadly; if I understand your meaning.... Maybe you're thinking the devil character is a daydream for the young female? I don't see that so much. I see him being real and sneaking up on her, which is why it would be sad.
For some reason, I want the devil character to be partially invisible, or partially obscured, in some way. Or maybe if there were a mirror where we see the reflection of the devil, but we don't see him first hand, it would seem more like a daydream?
But what strikes me the most is the facial expression of the female. There's just so much....depth of innocence and purity and youthful bliss in that face! It's truly a masterpiece by itself! And given how well that's achieved, I have to say it makes the rest of the image distasteful for me.
If she was not child-like, maybe more worldly....I can really imagine a comical older female who's past her prime - lots of bulging and sagging, maybe bad tattoos, huge earrings, bad hair color that's growing out, bad hair style, maybe self cut/styled (thinking of some Carol Burnett characters - not sure who is a more current comedienne, who portrays such a character). Anyway, a youthful devil sneaking up on her would be hilarious (especially if it's a daydream!) !!
And the other thing that strikes me (these aren't in order). I don't recall any of your drawings where we see the gnarly, sometimes partly skeletonized, or somewhat militant (guns, weapons), or just punks, either male or female character, in the same image with the sweet young female characters. So in the hands of the devil, I see the contrast of the gnarly, maybe evil character, almost conflicting with the young female. I just find it's an interesting contrast.
