Batman

You may want to say who inspired this drawing. It looks a lot like the late Micheal Turner. And since your Superman also looks like Turner's I'd suggest you add a line saying so. Especially if you are adding your pics to groups. If you try to pass it off as an original you could end up in a firestorm you may not be prepared for. You did a good job of honoring his style and I'd say keep it up, but give credit where credit is due.
