New Contributor: Over 75% rejection rate for 3D Renders “Quality Issue” Problem

Hello! I joined Adobe Stock a month ago, but I’m facing a 75% rejection rate for my 3D automobile renders due to 'Quality Issue.'

My question is: what can I do about this? My images are exported from 3D software at a high quality of 4K-8K, using 100 samples and a denoiser. They are in PNG format, properly cropped, with adequate titles and keywords. Despite all this, most of them are being rejected. I would like to know what I can do to increase my success rate. Recently, I even tried using an AI upscaler and an online AI artifacts denoiser, but the problem seems to remain the same.

I will attach a link to an image in its original format. Thanks!
