All of my images was denied. Help me, please.

Hey, guys, can you help me? I'm going through some difficulties with work and I'm old, which only makes things worse. I would like to try selling some images on AdobeStock but I'm having some trouble. I'm thinking about subscribing to Midjourney, but it's an investment that HAS TO WORK. I uploaded 10 AI-generated images and all were rejected for the same reason: 'excessive post-processing and/or noise.'

How can I get my images approved? After all, AI creates images on a small scale (1024x1024 pixels), and I used another AI for upscaling to avoid too much noise/artifacts, but my images were still rejected. I would appreciate any help.

ps: I cant pay for a good image upscaler. (I used imgupscaler . com). Maybe thats my only problem. You guys use 4x? 2x? which free image upscaler is working for you guys?
