I already posted this in a fanart sumbission, but I'll post it one more time ^__^ (with one more hint)
The rules of this game are to guess what movie inspired this sketch :D
The prize if you win this game is one fully colored request from moi :]

So here's the pic:

The hints so far are:

-It's NOT an anime movie
-The dude in this shetch does NOT look like the actual character in the movie (I was too lazy to make it look like him XD)
-The two non-people things in the sketch are an electric scooter (in the movie it's red) and an airplane
-The thing around the dude's neck is an earphone (notice how when he's in the upset crouched position the earphones are on)

OK, I gave you guys 2 new pretty gud hints, I hope someone gets it before I start having to give away actor names XD
