I really liked the extra particle effects you used, and I liked the transitions between clips. However, I think the (few) frags that should have looked impressive didn't because of the combination of STV demos and no crosshair. Those two things combined make the mouse movement look like everyone's mousepad is coated in honey.
Also, maybe I'm alone in thinking this but a crosshair should always be used in scout clips. Whenever I see a scout clip without a crosshair I think they're just trying to cover up the fact that they have no idea how to aim.
