Man, now I want to read an entire Batman run with your art.
I think @thepixelizer is right that the anatomy isn’t realistic, but honestly I quite like it and think it works. The Dark Knight Rides again was basically Frank Miller believing his own hype and not understanding his own work, with art and writing that are remarkably poor. It’s style over substance, but your interpretation has much more thought and care put into it. Bruce is clearly a bit past his prime, but still has it. He’s still as muscular as ever, just more bulky than trim. Your lighting is fantastic as always, fully capturing the vibe of Batman being ready to throw down with nothing held back.
Keep up the awesome work!
