Is this call correct?

Background: I'd been playing about as well as I ever have and it's paid off both in chips and respect at the table; VILLAIN seems like he understands the basics and will be a good player eventually - right now, though, I feel I've got him intimidated and overmatched.

Thoughts, criticisms, outright mockery? If it's a donk-tastic play, tell me - I realize it's a marginally appropriate call at best.
