a stereotypical and dull flash with frequent perspective problems, an absolute lack of sense of illumination and a very very ugly outlining for each character
I think that something that really grinds my gears about your "fbf style" is that you just make everything in frame by frame yet you dont add any definition to the characters, the limbs and legs keep changing shapes and there is pretty much no body consistency in any second of the animation. take a good screenshot and see arms and legs distortioned in freaky ways.
also, there are more things in life that dessu wanabbe anime fights with lots of filters and fast paced "action".
