Rejection of illustrations for quality reasons

Over the past three years, I've submitted 2700 illustrations, and only 36 have been rejected.
As for those 36, I uploaded them at first without knowing anything and just changed the background color, and there were too many uploaded ones with very similar fish scale patterns.
I've done some AI image work, but most of the reasons I've read on this forum are why AI images are rejected.
Seeing that they didn't tolerate even the smallest mistakes, I started to doubt whether I could actually pass.
Looking at that, I predicted that AI drawing judgment criteria would soon be applied to illustrations as well.
A few days ago, out of the 100 illustrations I uploaded with more care than usual, 20 were rejected en masse.
I expected something like this to happen, but when it actually happened, I felt so shocked and bleak.
Because I draw 100% vectors and upload png files, I rarely make quality mistakes.
But... if you apply the criteria for judging AI drawings, it is bound to make a lot of mistakes. People who draw directly make more mistakes than AI. No matter how carefully you draw, you can't perfectly draw all the intersections of lines in a very complex drawing.
Up until now, it was considered acceptable as it was included in the creator's intention, but I think it is unreasonable to apply AI drawing standards to human drawings.
But.. I think this could be an opportunity, because there can't be any more new illustrators.
I was amazed at how great your painting was, and I was terrified that it was rejected, because that's what happened to me and it's what will happen to me in the future.
I think it's sad but I have to accept it because it's something I expected.

This could be an opportunity, it could be a frustration, and I can't help but feel anxious about future earnings as I see AI expanding its scope to vector graphics.
If it's a rule that applies to everyone....then someone with skills like you might have an advantage. I guess you should accept it.

Hi @Andrew Lynchak 

The only issue I find is that the lines are not expanding smoothly as I zoom in. This is the case with all the files you post here.
