Framing could be improved and the camera set up is too grainy, for your next project try to set the camera up better. Have more shots then just close ups, you want to show the audience the locations. Acting can be heavily improved and definitely took the film down. Expect for the joker he was great! Its difficult to pull off a batman film but the main issue with this film is the locations. Locations for batman are very important. You seemed to film in abandoned buildings and didn't even show the buildings, that doesn't seem like a very good location for batman. Definitely should have casted someone older and better at acting for batman.
