The Vicar's design reminds me a bit of Boy Blue, but maybe that's just a knee-jerk from the Willingham association. It is also not a complaint. ;)
This is pretty funny, actually -- I've only seen an issue or two of Ironwood, and I haven't cared for it much. The thing that stood out, even more than the centaur-on-human porn, was that the word bubbles all seemed to be placed right where they'd distract most. I'll keep an eye out for collections if there's more humor in the series.
