quality issue

[Kudcia channel]

Hello, I'm am fairly new here, and all of photos rejected for quality issues, but I'd love to know more specifics,  so I can do better when submitting. I did use AI to upsize them and also taged as ai.  Any feedback will be most appreciated!  Thank. you.

Yep, but critiquing illustrations is not my strong suit. I'm sure someone will chime in. I don't see anything wrong that stand out to me, but the moderation has become so strict over the past few months. Half a year ago or so, I suspect this would have been accepted.

Yes. It needs cleaning up. That's just one particular area. There may be more. View your asset at 200% (that's what the moderators do), and correct as needed. Then try resubmitting.
