Are you going to say stuff like : 03:26:728 (4,5,1,2,3,4,5) - require some musical difference to support flow changes too?
My answer is a yes, or at least you should be able to explain that difference based on the mapping logics you've applied.
Reviewing from your replies, I'm pretty sure that you've got the point what I'm trying to say regarding the structures. Just that it seems you can't really understand "why" they are issues. Let me elaborate in that respect.
Beatmap is a secondary creation that reflects a particular song via placements, movements, visual concepts, rhythmic choices and several other mapping aspects. And reflecting a song as a map does not mean just simply giving an overall feeling as song goes by. It's about reflecting the musical aspects inside the song because as I've said, beatmap is a secondary creation based on the song.
A map does not exist its own without a music. Reflecting the song may be done in a different extent as what music aspect people prioritize, yet the essence remains the same. Objects that are combined with the mapping aspects I've mentioned before form a logic when corresponding with the song. That logic and correspondence show how the map is reflecting the song.
I've considered the continuous variation of patterns to be less corresponding to this particular song which made me feel the map lacking in structures. That's why I've asked for extra explanations to figure out if there were any backing logics that I've failed to detect. Some explanations were satisfactory, but for most points I've made, the common answer I've got is that you can't explain because there is no way to. Maybe it is hard to tell the reason for initial mapping concepts as it involve one's mapping style. But once a logic presents, it is possible to explain stuffs that are under those logics. Reasons for the flows, aesthetics, placements etc based on the mapping logic you wanted to express the structure of music-beatmap correlation.
You already know yourself that this kind of stuff presents in your previous maps. Even the ones I've nominated, you say. Those issue presented yet deserved my nomination because each map had a much bigger value that compensates the weak structure in my opinion. (Won't be mentioning those individually since I don't think this is the appropriate spot for that.) If I decided to decline a nomination for those maps despite the greater values I've felt, there would be literally 0 beatmaps to nominate in this game for me.
If you think I'm just nitpicking over extremely minor issues that you didn't even considered as an issue, then I've got to say congratulations. It is a mapping perspective that you never seriously considered while mapping until now as a mapper, yet something extremely essential in the very grounds of mapping which you can consider to improve further as a mapper.
You are really an expert in designing objects in technical ways. I can say your skills are top class as far as I've saw from this game. But the ones I'm mentioning here are the weakness of your mappings. It's not only at this map 'alien' as you've well explained yourself. You may disagree personally with my decision on being too harsh, but please understand that my opinion did not pop out of 0 basis.
I hope I've got nothing more to add for now.
