Why was this deleted?

I stumbled upon this piece by an artist I enjoy and I do not comprehend why this would be deleted.

This is such higher quality than SO many pieces I see approved and I have NO idea why this would be deleted for quality.
There's nothing wrong with this image. It's gorgeous.
Can it be reconsidered please?
Thank you.

We have a topic for this: topic #7934

Also, the argument "worse things have been approved" will never help your cause, it's the worst reason you could make to have something undeleted/approved.

Thanks. I wasn't aware of this thread.

I'm just honestly surprised by a lot of what does get approved then seeing things like this that are just fine and not approved. It never makes sense to me.
And I don't see what's so wrong about that.
