First!!
[General]Minor Timing-Issue:
Timing for the later parts is a bit early (I get late hits in the last ~20%). Seems to be a minor BPM delay that can be fixed by removing the (Red) Timing Points @38218 and @40945 (not needed anyway). The only thing the Timing Points do is making the big tick of the metronome fit with 00:38:218 (1) - You change the metronome back to "normal" with @40945 anyway so I suggest not using those two Timing Points at all. Use BPM 109,980 instead wich seems to be more accurate in the later parts of the song.
Tested with DT/HR/HD and set OD10 on 'Yellow Flower' with ~98% accuracy. You may give it a try or just leave it as is
[Yellow Flower]00:45:854 - delayed break works really great here!
01:39:327 (4,1) - not "wrong" but I suggest a less complicated beat placement (the slider start on the red tick might confuse beginners) for this difficulty. Use a circle for (4) and move (1) back to where (4) ended, add repeat, replace pattern to make it fit:
http://puu.sh/1clZE01:49:147 (2) - Seems you wanted to break the 1/1 pattern but this slider just plays and sounds awkward. You could try to map (2) as a circle and start a 1x repeat slider on the following downbeat instead:
http://puu.sh/1cm31[Blue Flower]Many Patterns seem rather cramped, I suggest using circle size +1 to make it a bit more clear
00:00:037 (1) - repeat doesn't follow anything, I suggest using a no-repeat 1/1 slider instead
http://puu.sh/1cm6w01:39:308 (3,1) - I'd suggest something similar to what I did for 'Yellow Flower' but it is up to you (the violin is still holding out between those two sliders so it would still fit if you close the gap by mapping a slider from the downbeat 01:39:854 up to the start of the vocals 01:40:672). The slider start on the red tick plays just a bit weird (feels unnatural especially with hidden)
02:25:126 (4,1) - (1) might be a bit hard to read with the turn hidden unter (4). You could use a simple curved slider to avoid that (similar to 02:37:126 (4,5)).
[Red Flower]00:01:673 (1) - I don't have any problems with those sliders personally (I think they are great!) and I suggest you try to keep those even if they are "discouraged" (but not unrankable - checked with Garven to be sure)
01:02:217 (1,2) - try not to (partially) hide the repeat of (2) under the sliderbody of (1). Make it a bit less cramped and it should look better, too.
01:16:945 (1,2) - avoid hiding the start of the slider (2) under the sliderbody of (1). I guess this is still a major issue but I am not 100% up to date with the ranking criteria. Personally I think hiding a maximum of ~33% of the starting-point should be no problem. Just move it a bit so it is less hidden.
01:27:581 (3,4) - the stacking breaks the flow of the movement completely. I suggest deleting (3) and moving (4) back to where (3) was then add a repeat:
http://puu.sh/1cmQl02:14:217 (1,2) - hiding the slider ending under the previous slider should be ok but it is not recommended - your choice
02:27:308 (1) - cosmetic: rotate slider by -15° (clockwise), selection centre to avoid the overlap with the previous slider, adjust the following 2 circles to match new slider ending
02:33:308 (3,1) - check stacking (circle is not stacked properly)
Otherwise this map is really enjoyable!
That should be enough for the first mod of this set. PM me for a recheck after the SB and Skin-Elements are finished if you want
