Thank You guys, i really appreciate your feedback!

Actually, this 'video sync to chillstep beats' was my first try ever, and i don't really like that sorta things, but for this intro/promo vid, i found that with those it can be more 'acceptable' than without any slip/shift effect. Yeah, at the end it could be a bit annoying, and i will take your advice (what is enough, and still colourful). The particals (and other overlays/effect) are a bit overused imho - eg. In lfs drift videos, therefore i tried to minimalize the use of those overlays (the particals were just a downloaded free overlay video, not any aae plugin generated thingy bit, unfortunately that is'nt familiar to me).
Thank You gentlemen again, for me it is very nice to read all of your comments! I will try to do more vids, and try to improve as well.
Cheers! wody21
