That dude with the Trixie on his head is very expressive. Probably my favorite one of the bunch. All are pretty good and colorful.
He gave me a request of him being tired and hungover. I never drew the latter, but I did drawn drunk ponies before. And i've been up enough nights to master tired pones. Expression wise, this one was a refresher with a new angle and faicial expression.

Also, the guy is wonderful. He has a really nice style and is just a pleasure to be with.
