The first chapter is a bit on the short side, but it's ok. The whole thing is good save for the fact that it wasn't a really strong start, though I'm sure it'll get better. I really love Harlequinn and the Joker though. :)
I'm sorry! But see, that's the major diference. You can't put a hero with superpowers with a clown without any. That's the difference between Marvel and DC. I'm gonna stick with DC. And thanks!
I really like what you have here, I used to adore Batman <3
