I'd remove 00:12:132 + 00:19:332 e.t.c to instead be used as a short break as the beat there kind of sounds like it's more or less " background noise " and feels awkward hitting.
00:49:932 - 00:50:532 isn't the same as the previous triplet where the first 2 beats are the same and the last one different. It's instead the last 2 beats being the same therefore I suggest making it {ka don don}
