Check these two cool looking character designs for Batman and Robin. They were created by Artist Coran "Kizer" Stone, and this is what the artist had to say about them in his notes:
The man of the Darkness. That Man in the Night. Batman. Thought I'd redesign the dude once again but show him in his late 30's to early 40's this time. Popped a bit of Recon in there.
My Tim Drake is mischevous. Robins always fun.
I really enjoy Stone's art. I've shared a lot of his stuff over the years. He just has such a badass style.
