Hmhmhmm
I watched the whole vid and I can definitely say: Not impressed.
What your combo video lacked was:
1. A variety of combo's. It was mostly (random move) to spike.
2. Too much online matches. A lot of those combo's I just thought "Wow, I can almost taste the amount of lag". Leave online clips out of your video's.
3. Not enough Flame Choke stuff. There were 1 or 2 nice clips where I thought "Hey a good clip" and then you went back to the spikes.
4. The music was pretty bad... Don't get music off Newgrounds, go to OCRemix for quality remixes. The second song was in particular rather painful. Good Zelda music can always be found at ZREO (seriously, google it sometime).
5. The clips were kind of dark.. It was still good to see, but could've been fixed.
6. Too long for a Brawl video... 6-7 minutes is what you wanna aim for. No need for credits if you don't want them and for god's sake - no need to list everybody. You can just do that in the comments. The whole 'Bloopers/showing how good my opponents are' bits at the end weren't all that impressive either.
7. Don't use stupid opponents... Honestly, there was one clip in particular where Lucario constantly just rolled back into your hits.
Just work on that and you'll have a pretty good combo vid next time.
