This is the thing about Kazuyoshi. He just isnt good. You can look at his videos and photography on the 'talent' company site he is signed too.

They are just uninspired and quite horribly made. Someone mentioned that if it wasnt announced that he did GREEN then we'd all love it. Bull. I saw it before I realised it was him who had done it and I still thought it was awful. Yes the locations are nice but thats up to the set designers - He didnt make good use of it whatsoever and the pacing was just utterly laughable.
Is he improving? Well lets be honest a 10 thumbed moron could do a better video than Mirrorcle World so in that essence, yes. But as in actually doing better shots, tightening up pacing and making the video flow better than asif the video was a river of bricks - No.
