does quality issue has connection with file size??

Hi ​@shanto2003 ,

When zoomed I can see noise grains in the darker areas.

Best wishes

Hello,

I think there is also another issue; the white balance is off. There is a green cast to the photo. Be careful of the kind of background that is used/generated and the skin tones.

When AI-generated images are enlarged, fine details can get crushed or the images can take on unexpected shapes.
You might not notice this when looking at the entire screen, but if you zoom in to 100% and check the images, you can see the defects more clearly.
The Adobe Stock checkers also zoom in to 100% when checking the images.

File size is not necessarily a quality issue. You wouldn’t have been able to upload the image if it didn’t meet the minimum file size requirements. Zoom in and inspect the details carefully. There are numerous drawing issues in this image. Here are a few.

No, file size is not a quality issue. There’s a darker green line going down the left-hand side and the hair rendering is unnatural in areas. It might also be too tightly cropped. A little more shoulder or including the top of her head would be more pleasing. And move her to the right to allow for copy.
