I pre-ordered the comic at my local comic store and the clerk commented that the art in the hooves preview looked really good.
I'm annoyed at the facial expression in one panel and worried that the hooves will clop on the ceiling, but honestly, I think it looks good overall too. I'm looking forward to this.
Again, as long as another comic artist isn't being stolen from, I don't really care how the art was composed. I can't help but wonder if we'd be analyzing this so hard if it weren't for the Greg/Tristan situation getting us all pissed off.
