Quality Issues rejection , Please review

I'd look at the upscaling step first. 11264 x 6144 only tells you the file is large; it doesn't mean the original detail survived. Upscayl can smooth texture, invent repeated detail, or create halos around hard edges, so compare the pre-upscale image and final export side by side at 100%.

On these files, inspect the hockey stick shaft, the edge around the puck, and the white artifacts already mentioned. If those defects appear only after enlargement, return to the source; if the source already meets Adobe's minimum, don't upscale it just to make it bigger. If the defects are present in the source, another upscale won't repair them, so regenerate or discard the image.

I wrote a longer breakdown of this exact kind of refusal, using three real Quality Issues cases to show when to repair, regenerate, or discard. If you'd like the examples, they're here: https://www.stockphotoscout.com/en/guides/adobe-stock-quality-issues-rejection-ai-images

Stock is NOT an art gallery, it’s a global assets service. Stock customers want commercial quality images for use in professional projects. IMO, your images are too dark and lack commercial value for print, digital media, marketing, or merchandise.

Ask yourself who will buy this, and what will they use it for?  Compare your content with other Stock inventory to see what’s expected. Also read your Contributor User guide.

Hope that helps.

I think the first image is a little too abstract and soft with respect to what Adobe is looking for these days. And while I always hesitate to claim that Adobe systematically rejects black and white assets, since I’ve had some accepted myself, Adobe does prefer color and I probably wouldn’t bother submitting black and white assets today, given Adobe’s increasingly strict quality standards. But ​@Oh.N8’s comment is right on about the white artifacts being in need of cleaning up.

Hey ​@SIKHA30793578jmcc 

Very cool images.
the image itself is a bit too dark. 

Next to the hockey stick and above the puck there are some white artifacts that could be removed.

Cheers

Maybe the shaft was one of the issues, but that’s just a guess.

The overall look is cool, and I think different compositions and angles could bring out your idea better.
