Photos not accepted because of technical issues

You did not upload the full scale pictures, so there is no possibility to check the focus and other possible artefacts. It is indeed impossible to check a whole repertoire of issues. So there are only two remarks from me:

This is a typical asset that needs different editing in different areas. 

1) light up the shadows. The walls will probably need a different treatment than the persons. The woman needs more shadow lifting than the man.

2) lower the exposureand augment the contrast.

3) enhance the local contrast here

You have here in two places identifiers left, that could lead to an IP refusal. In addition, I see chromatic noise in the T-shirt. 

Thanks to everyone for taking her/his time to review and thinking about it.

First i need to assure, that every photo was processed, not to the possible limits but there was some processing. 😉

Maybe i could have done more regarding contrast and exposure. But also be assured that focus was always there and if the DOF is not very deep this wasn't by accident. Maybe i should do more processing but then some of them will not longer be a picture of reality. On the other side I wonder why these picture were accepted by any other Stockphotoagency (Shutterstock, Gettys,...). Next time I will turn up the controls 😉

Thanks to everyone!

Vineyard 2.jpeg - the foreground is not in sharp focus and is a bit underexposed, whereas the sky is overexposed. Did you edit these images?

 As a personal tast , I see shalow DOF in a landscape shot which IMPO not match the view .

In this one, I'd say it was haze, overexposure, and lack of contrast. 

The first photo focus and color tint are issues.

Looking at all your photos, I see issues like: sharpness, or exposure, or contrast,  or color, and framing. You need to do some post processing. out of camera is not enough.
For instance:
