Dom, I did get the feeling that you wanted to use EVERY effect you've learned (and mastered

) so far. In that respect, there wasn't much continuity. If it was a showreel, I'd say emphasise the effects MORE (maybe shorter bursts of each "scene").
You've definately got the camera technique on a board down to a tee, but you do get an excess amount of noice from the wheels. Have you tried reducing this?
Gotta say I like your videos though
