Yeah, you're right! This is much better than your previous maps.
Still, the stuff that I didn't like too much:
00:25:093 (7,8) - Spacing like this. I actually prefer placing notes like these a lot farther. Here you just slow down very much, that kinda breaks the flow sometimes. It makes too much contrast with fast jumps there. I'd place it somewhere in the bottom of the screen or so. If you want to fix it without breaking the whole patterns, try to flip whole big parts. For example, select 00:25:593 (8,1,2,3,4,5,6) - and press Ctrl+J.
00:37:093 (7,1) - 01:02:593 (3,1) - 02:13:093 (7,8) - These spacings seem to be more enjoyable for me.
01:07:593 (1,2,3) - Kiai time modding! These are not mapped on the bubbles. These are actually mapped almost on nothing (middle note at least).
Actually, I like this bubble-sound idea really much. It's fun and somehow new
What could I suggest about patterns, shapes... Do not focus on straight lines. 01:31:843 (2,3,4) - Stuff like this is not any popular nowadays, it's way too plain and "boring", I can say. It could be better to make something curved, play with angles and stuff.
01:39:843 (2,3,4,5,6) - This is super-boring.
02:09:843 (1,2) - This is way better. Looks funny and plays nicely too.
I guess that symmetry is your best friend, however, I'd suggest you to try to map more "free" patterns. I feel constrained when I play symmetry. That might be just my opinion though, the map looks fine anyway.
02:32:093 (1) - Part after this one looks quite cool, btw o: I like it.
Though, 02:41:343 (1,2) - this can probably be considered as 1/4 rhythm (because there was plenty of it before, and the sliders are close enough), so I'd suggest to move (2) a bit higher.
02:43:843 (1,2,3,4,5) - Rotating this by 15° anti-clockwise makes it to look quite fancy! If you check out Reiji-RJ, TicClick, yeahyeahyeahhh and many other popular nowadays mappers, you'll notice that they use
a lot of straight sliders, rotated 15°-20° in any direction. It looks neater than old straight patterns that were strictly horizontal and vertical. But again, just my opinion. It's your choice if you should follow it.
04:27:843 (1,2,3) - This as an example. And not only rotating works to make it more interesting, changing these sliders to curved ones is a nice idea too. Or try sliders like this:
http://puu.sh/233en02:48:843 - This note is really important, I'd place a circle here and move the spinner a bit later.
03:17:843 (1,2,3,4) - Again, I should say that patterns like "ten sliders starting at one point" are boring as hell. It's when you just stay at one point with your cursor, holding and releasing the button. No actual movement or anything... It's better to avoid this if you want to make a fun diff.
And again something about kiai: I think you can add some sliders there. Just replacing some pairs of circles with a single slider can do a good job (just be sure that such sliders start at heavier tick (white or red)):
04:25:843 (1,2,3) - Oh, and this is quite hard to read. Try to redo it.
And I like the last ending sliders, nicely done :>
Overall: 8.5/10 (quite high!)
