It is purty, has a tender mood. The lines could use some completion, for instance on the necks and Lucifer's jaw - because I'm assuming that Lucifer is the one with the black hair? I like the lines of their eyes and eyebrows almost mimicking each other, but turned in different ways, like the happy/sad faces at a theatre. The background doesn't seem to fit in, it looks like bubbles from a lavalamp.
And I think you should either blur the top or leave the image un-blurred.
