Leo's Flower View:
04:47:499 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4) - I find that kind of hard to read. I hit it while playing, but had my problems with it. If you really want to keep it, do so, but I just want to note that this is quite hard to play/read, to me anyways.
04:54:883 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4) - ^
05:13:344 - Eh, do you really have to use 2.0 sections? Now that we have custom slider speeds you could just use 1.5 or so, that wouldn't be so extreme. Though, as you have a warning, it still works. Keep if you must, change if you can.
Collab Flower View:
02:58:113 (4) - Add new combo? =P
03:17:959 (3,4,5,6,7) - This spacing change looks a bit weird, but iiiiiiiiiit's playable... if you want to keep it.
04:42:883 (1,1,2,3,1) - These new combos are a bit ugly and don't quite make sense
04:54:883 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4) - Again, these overlaps are hard to read.
05:10:806 (1) - Remove New Combo?
05:09:652 (1,2,3,4,1,1,2,3,1,2,3,4,1,2,3,4) - Again, these overlaps are hard to read.
I guess none of this is compulsory, but it'd certainly improve the map quality to look into some of these issues. Nice mapset though.
