Overall everything seems fine. BUT :

Difficulties ULTRA and MASTER seem kind of overdone. There are quite interesting technics which were used, but they don't seem to be fit with music. At least for me. MASTER difficulty has such patterns like this 00:08:567 (5,6,7,8) - 00:12:424 (1,2,3,4,5,6,7,8) - 00:14:246 (2,3,4,5,6) - 00:19:816 (1,2,3,4,5,1) - and etc. Imho - they do not fit the music, they are just making difficulty harder, but not better. Please, accept this as my personal opinion.

- 00:20:138 (4) - i suggest to put new combo. It was pretty hard to read by first look

- 00:41:351 (5) - ^

- 00:45:208 (7) - ^

- 01:20:349 (2) - hard to read. Consider to make '2' visible

- 00:29:458 (4) - unreadable

- 00:31:172 (4) -

- 00:04:282 (8) - new combo

- 00:11:782 (11) - ^

- 00:02:032 (1,2) - hard to read

- 00:15:746 (8) - i suggest to replace slider somewhere else to avoid covering.

- 00:10:282 (4) - i suggest to replace slider somewhere else to avoid covering
