I felt the second one went on a bit too long and her mouth wasn't opening nearly wide enough to sell the opera singing, but that was still hilarious. I agree with what's been said about character and background art so far.
I'm glad you thought it was hilarious. I don't see how second skit being a bit longer was a problem, since the whole thing was under 2 minutes. As for the mouth not opening wide enough for signing opera, I will work on lip-syncing more realistically in the future.
