Ai images rejected because of quality issues

Embedding an sRGB file into an AI images is also something that's easy to forget to do. I've set my "Edit... Color Settings" to the following:

Also, as far as I could tell, none of these images have an sRGB color profile. In fact, they have no assigned profile at all, since most AI programs don't appear to insert one. I doubt this would be a reason for rejection, but Adobe does specifically state that submissions should have an embedded sRGB profile.

Being a bright, sunny day, I think the shadows could have been opened up quite a bit.

Just a couple minor issues that popped out to me.

I looked at a few, and found drawings errors in each.

Fur does not create a hard edge. You need a soft blend into the background.

In addition, you see aliasing in this 100%-view screenshot.

The white border around the paw:

The paw itself does not look naturally.

Difference in the eyes, even that it is an error, I doubt that the moderator refused or would refuse for such a reason.

Side view dog: besides the wrong white balance, you have colour noise:

There is colour clipping:

The nose is weird (again, I do not think the moderator would refuse for this):

The lungs:

That is, for once, a nice picture idea.

There are artefacts and colour clipping, if you look at your asset at 100%:

The hands:

1) the fingers don't look correct

2) there is noise

I also find that the contrast is not right.

The histogram is showing missing blacks and missing whites.

Geometry artefact (left hand):

Colour artefact (right hand):

Hat:

Artefacts and aliasing:

The hat's resolution is not good enough. It looks like a badly upsized image.

Molecular structure:

I doubt that this one is correct, even, if you would correct the visual errors:

In addition, it is noisy. Be careful with such assets. You can be banned for this, as you pretend showing the real thing.

The woman:

Spring:

noise, white balance, aliasing, drawing errors and missing contrasts:

(next time post only one or two assets, subsequently, you will probably yourself able to see the errors. All errors here are easy catches.)
