You know, I wouldn't mind Jeanty's art very much if it wasn't because he was doing Buffy. I've had a look around his website, and some of his stuff is gorgeous. It's just that his depiction of that specific world really does nothing for me. (And yeah, the weird proportions don't help.)

Urru's art OTOH hand captures the spirit of AtS very well. Not that I don't adore his work, full stop, but it works with the 'verse, not against it.
