Detailed
Well I see this is a very detailed piece of work anyways. Seems to be bit of a break from the rest of your work which has a silly fun textured feel to it whereas this one has more of a serious and far more detailed look to it. I am going to guess this was a commission piece? Looks very nicely drawn though.
The background is a nice and simple white that fades to pink which seems fitting as a vampire is going to bite the only person that loves him right? The background is nice though.
The girl herself looks like she is just trying to relax so the bite will not hurt as much when she turns and becomes a vampire though. Her school girl outfit seems to tell a bit about her and the fact that she is still in high school. Her face and hair make her look cute yet shy.
The guy on the other hand seems to be the same except far older than possibly most of the teachers there but still going because his siblings are possibly going there with him and he wants to make sure they do not harm anyone unless threatened badly. His hair and fangs look nice.
Overall, really nice piece of art, I like how this one turned out.
