teasers have to be intense edits if their going to be effective and worth while. you dont want to show skating clips i get that, and you shouldnt. but thats why you have to show something interesting.
I've made a shit load of teasers. People are usually well receptive to them. The idea is to but hours of work in a short ass teaser to make it interesting
maybe make if funny, over the top and slighty stupid
