I agree with chainsmoke11. This is the way I like to see him. Totally gritty. When you start adding all of the details and muscle him up, he gets too pretty. Batman is about mood and design.
This is the way I like to see Batman drawn. I don't like when artists draw muscles on the costume. This is a great, simplistic design that looks practical. I would like to see this design used in a Batman movie someday. Great job on this.
