Quality issues rejection

The shoulder is much too large. The design of the necklace is inconsistent.

Check the ears and eyes with your 2 other assets. The skin texture is more than strange. The picture above has a blurred skin part, like a Photoshop edit that went bad. You can argue about the tattoos, but if my tattoo artist would deliver such a bad job, like the girls back, I would kill him.

The girl has very visible issues with blending into the background.

Just looking at your butterfly image: look at the antennas, the blending of the butterflies and the flowers. 

I've only marked some of the errors.

Look at your rendering lines. There are errors in all 3 images.
