Posting your video and asking for positive comments only makes no sense... by posting, you are welcoming criticism. if nobody criticizes you, great. if people do criticize you, just learn from your mistakes so you do a better job next time!
by requesting and receiving positive comments only, you will never know what you are doing wrong.
that said, keep it up! if you want to take my advice and get serious (and respectful) critiques that will help you become better filmmakers (and skiers), post your edit in the Media & Arts forum!!
