I know you haven't even seen the first issue yet, but I'm well into the fourth issue of my five-issue IDW Love and Capes series. I thought I'd share the cover for #4.
The covers are often the hardest part. I treat them like one-panel gags that don't need to have anything to do with the story inside. Sometimes they do, of course, but I don't feel bound by that. They're kind of like Betty and Veronica covers that way.
Complicating things is that IDW and I are doing variant covers for each issue. My friend Chris Bailey, animation director of Hop, Alvin and the Chipmunks and way more than you can imagine is doing the alternate cover for this one. He'd asked for a layout, kind of an idea starter, and we were working on one that was okay, but didn't quite sing.
Then, I had an idea for my cover. As I started to lay it out, I realized that it would be a good Thom Zahler cover, but it'd be an amazing Chris Bailey cover. So I contacted Chris and said "Hey, if you're not too far, would this be a better cover." He said yes, and I have since seen that cover. It's achingly beautiful, and I'll be sharing that soon. But not right now.
Unfortunately, that left me without a cover. One of the ways I figure out the cover image is figure out what I haven't done. That's how Darkblade appeared on the cover of #8. I realized one of my favorite characters, Doctor Karma, hasn't appeared on a cover, so I thought about him.
I had this idea for Karma to be at a talent show, sawing Mark in half with Abby as his assistant. Too complicated, though. It didn't work… and then I thought: What about Abby as the magician?
So, what I wound up creating was this cover where Abby's using Mark's powers to fake a trick. I was a little worried about it, as for the cover to be funny, you have to know that Mark is the Crusader. There's no visual cue. Yeah, this is the 17th issue of Love and Capes, but every issue is someone's first. After 
showing it around to my Secret Society of Super-Reviewers and on the Love and Capes Facebook page, I was encouraged to go ahead with the secret identity cover.
This is the cover I came up with. I think it's pretty funny, maybe one of the best covers in this run.
Issue five, though, is no problem. I've known that cover since I started this series. It's gonna be a stunner.
