The characters are Ren from DearS, and Kazami Mizuho from Onegai Teacher.
It took me a little while to finish this one, but I think it looks fine
I don't know anything about these characters but searching references of Mizuho, I noticed that there are tons of fan art, figurines and stuff about her, didn't know she was so popular, hope my drawing could be good enough then
This is a Fan art, and these characters belongs to their respective owners.
Hope you like it
