I never followed up after mentioning that I was heading out to watch The Dark Knight. No surprise--I really liked it. What might surprise you, is that my favorite element in both movies is Gary Oldman's performance as Lieutenant Jim Gordon, later promoted to his trademark rank of Commissioner.
I drew this right after seeing the movie, but it's only loosely based on Gary Oldman, drawn without looking at reference. More Bat-stuff next time. Perhaps even the Man himself?
