01:28:717 (2) - I think this should get some movement since the intensity throughout 01:28:517 (1,2,3) are pretty similar.
true but I think it should be fine to keep as is, im afraid if it will be too sharp for the movement if I put antiflow after the 1/4 hdash 01:28:450 (8,1) -
01:30:650 (1,2) - Rhythm structure here seems a bit awkward. The earlier section which has lower pitched guitars as mainly 1/2 patterns, yet the higher pitched ones are replaced with sliders. I think going with the structure you had @ 01:29:583 (1,2,3,4) would be best.
