The transitions for both clips work quite well because of the visual association. With the scene with the police, does it ever escalate to the point where a punch is thrown? Just thinking that a smash cut from a punch to a shot of him in the Japanese cell might be a nice touch.
Will the dialogue in these scenes have any relevance to your overall narrative though? If you are going for something that is totally surreal, and none of the dialogue is going to be relevant, then you would be better served trimming scenes down significantly so as to achieve something more visceral. Otherwise, you'll need to make sure that the scenes remain effective/entertaining even out of context, or edit the dialogue so that there is some kind of thematic thread running throughout. I'm not familiar with these films, but personally, I would feel no inclination to pay attention to scenes unless: A, I knew the scenes had relevance to each other, or B, things change so often that i'm drawn in by the unpredictability and pace of things. Even in something as experimental as this, it will be necessary for there to be a sense of an overarching narrative, even if it is intentionally impenetrable.
