Extremely well done
This feels like a legitimite way to start off Batman 3, and it sets up an interesting conflict between Gordon and the detective. The animation and artwork were good, the perspectives and scenes in general struck me the most though.
I assume this took a heck of a long time to make, but with something like this you could make a mini series (maybe 4 to 5 animations in total) and you'd be able to tell an amazing story!
If you ever get to do something on those lines with this try and get a musician to make some soundtracks for you, it'd be amazing :)
Great stuff man! Keep it up!
