That was a rather interesting but still a bit of an over-simple concept. It worked nicely though and was an entertaining video to watch thru. Cropping the backgrounds from the running animations always takes time and effort, one could though ask if you're over-using this style? In recent videos it has been done a lot and rarely used in a creative way. Yours have so far been expectional. The guestion is how long can you keep it up, if you always have to come up with something new?
My only real nag about the video is that the running became really old really fast and the song didn't emphasize the racing concept that much. I also kinda missed the finishing because the whole race stopped so suddenly, just like Naruto did.
