asking for arejected by "quality issues" despite consistency with previous uploads

I’m usually fine if there is a rejection in any image stock selling, especially in quality issues, but this rejection is kind of weird. Because all of my uploaded illustration have the same resolution, same sizes, same brush preset (even the size of the brush), same export procedure, maybe not in some quality but overall its almost the same in every aspect.

But today my uploaded batch is rejected and it was making me “whaaat???”, i’m really questioning about the consictency of your image stock reviewer team. because last month i have some illustrations that im really questioning it myself like “is this  going to be accepted? i don’t think it will” but it’s was surprisingly accepted! lmao.
