IF - Duet

This is the illustration I did this week for Illustration Friday.
It doesn't even look finished to me, but here it's Thursday night and I really need a shower right now. Moreover tomorrow I'm going to leave for the weekend and I won't have any chance to finish this. But I've work on it the whole week (here and there, in my spare moments... the truth is I'm so damned slow) and I don't want to just leave it there. So here it is.
