No worries, I was just putting my opinion to words.
Fundamentally there is nothing wrong with this map.
The reason why I referred to the triplets being random is that there is no supporting instrument in the music hence it's randomly overmapped, but you are right with your reasoning that if you overmap consistently it becomes less random.
There's also nothing wrong with using 3/4 sliders the way you did, it's just a personal dislike that I have because often they play and sound weird which disrupts the general pace of a map.
I hope you don't feel discouraged, this being your first map in this fashion is nothing to be ashamed of.. afterall you learn a lot from using new methods.
Generally speaking the map is fine, has a nice layout, interesting patterns and sliders.
The things I pointed out are just personal distastes.
Good luck~
Edit:
Forgot to mention;
03:14:251 (1,2,3,4) - and 03:15:635 (1,2,3,4) - sound like they should be 1/3 snap instead
03:24:405 (1,2,3,4) - is correctly snapped with 1/4
Listening to 25% playback rate on such high bpm still makes it difficult to hear out the correct snapping, so it's easy to make mistakes on such parts.
I am not even sure myself with this, but it sounds more appropriate to me.
