Be more imaginative with what you can do after u boost them down and what combos you can do. Also, take advantage of the fact that you do not need to do the 2nd part of weapon three to do the boost down. You may be better off dashing off and finishing the kill using boomerangs (there's a few times where you didn't really need to go for the 2nd swing).
Sometimes i find you not doing much even though ur dashing around alot. You weren't really getting into a better position doing that and you always tend to wait for a beamspec to end (its not always bad, but it's not always good).
But you did pay attention as a rock, didn't go suicidal and seemed to SS properly =)
overall good video!
