It was good for your first edits. a fiew pointers would be get a tripod or use the one u have the shots were really shaky. At night with the lights film with the light behind you not infront of you so the rider isint a shaddow.
Wow the first 2 vids sucked really bad. Absolutely no lighting on the first one and its some boring jib. The second one has kids doing crappy tricks on a bad quality camera with the bad quality cameraman. But that's just my opinion.
