01:03:900 (4,5) - would add hyper on both 3~4 and 4~5 because the guitar's pitch goes higher
03:23:549 (8,1,2) - tbh I don't think you really know how much of a difficulty spike this one pattern is (and how out of place it is with the rest of your map)
I fully understand wanting to make the final stream go off with a big bang, but this pattern is the only time that an extra antiflow movement is added in the whole map which makes it feel more annoying rather than coming out as a big bang
I would HEAVILY recommend making 03:23:707 (1) - vertical, it matches 03:23:075 (5) - right before it and keeps the same style that has been used prior in the map, without being a massive diffspike
