ok I know you said keep it positive but you cant get any help out of positive advice so I am going to post the best constructive criticism i can.
First I am not a pro and my editing arent the greatest but i know a few things.
1. Dont repeat tricks. i was stoked when i saw the kid frontflip off the box, then i realized he had a celtics jersey on, ( go nuggets!). but then when i saw it the second time it wasnt quite as nice looking.
2. grab your spins. you will get so much shit on here if you are pencil spinning. we dont care if you can back and spin up to 7 like a retard. If you can backflip with a nice tail grab and spin 7 with a sick jap then we will praise you with some skill.
3. Only use your good shots. the second time when the kid front flipped out of the box and landed on his back doesnt prove anything except for thee fact that he can ALMOST frontflip out of a box. Just like who cares that i almost got with your mommy last night. no one will care un less i actually pulled it of and gave it to her.
I hope this helps and doesnt come of as prick like. except for the part about your mom.
