Rejected neuro pictures

You did not embed the sRGB colour profile, as required (see the contributor manual).

The cat:

Aliasing and pixelation.

Cut-off fur. There are more of these errors around.

Artefacts due to upscaling. I suspect the pixels originally being nearer together, but that this size, this gap fill-up does not make sense.

The eggs on a plate:

The same issues as with the cat:

Pixelation and aliasing.

Colour noise, and around the tomatoes is a kind of border.

There is a white border. That would be a Non-Compliant image refusal. Moderators refuse on the first error they see, so they don't check the whole image. There is always a possibility that there are other refusal reasons on top of the given reason.

What is this element?

Why is this blurred?

Polar Bear: You see it, your up-scaler is not working correctly:

You also have that white border right and bottom that is not allowed.

The white border is also present in the next picture, the fire place:

As for the rest, it exposes massively artefacts as seen at 100%:

I won't check the other pictures, you see the problems, and they are more or less always the same. You need to check your pictures at 100% and correct all errors before (re-)submitting.

The wording is always the same and very vague - quality problems.

44AngelWomen.jpg - her eyes are different colors

67OldWomanlFuturist.jpg - the facial wrinkles are really exaggerated/unrralistic. The eyeglasses have no stems .

Poorly rendered tomatoe in 378Glazed; There appear to be some stars in FRONT of the moon in 119Camping3 in addition to looking more like another planet than the moon; 62CupidGirl...her teeth maybe? Eyes look realistic while her mouth looks cartoonish; weird earlobes in 67OldWoman; check out the pupils in 55AngelWomen.

In 413cat4 there are artifacts around the edges. These can be seen at higher magnification.

To me they look really good. However, there are small problems - with the camping chair, the pink lines at the bottom of the cupid's wings and the nostrils being of different sizes in Angel Woman. Otherwise it looks great to me. Must be good apps you are using or you have had lots of post processing work with the images ...
