Batman and Robin: Sneak Attack

Here we have poor Batman being randomly tackled by his extremely hyperactive new Robin, my OC, Jack. Jack has a rather long and hopefully complicated story that I'm not quite ready to reveal, but he exists on another Earth/dimension, where certain events lead to him becoming the next Robin after Dick Grayson, instead of Jason Todd, Tim Drake and the others (although they do still exist. It's just that circumstances lead to Jack beating them to it, unintentionally).

Batman isn't just sitting on air. Really! He's just sitting on a stool or something. I was going to draw the Batcomputer and a nice, big, comfy chair, but it just wasn't working out, so I did sort a character study instead. At least, I suppose that's what I should call it.
