That video has about the same skill level as your other weird set up in your garage videos, but that was way better just because of better spots. If you say that's an old video, go back to those spots and do more tricks and stuff, at one point I saw you jump a three set without a tailwhip or any tricks, so if you just threw in a tailwhip it'd be that much better. Nice video btw.
Liked some of the stuff, I dont see the point of doing a long manual into a stall on a curb. Learn not to land on your back wheel, It makes some tricks harder and sloppy looking (I think thats whoy you couldnt land the big drop), and also destroys your back wheel so lean forward and put some pressure on your hands when landing. And go with as much speed as you can when doing that drop and you will land it.
