I like the detailing in this one. Despite of being a skeleton, for some reason it does not make me associate it with death, but a character in general going through an emotion. I also like the use of constellations in the background. Some say the future is written in the stars and come to think of it, midterms might be one time when the writing may become a bit clearer.
Talking about characters, seeing how you have made also other pictures with a skeleton in them, looks like you do or might have a character-thing going on. Meaning, something personal and recognizable for your works in particular. Can't be a bad thing.
