Foto rejected - need some guidance on the reasons.

4149:

Many, many sensor spots. You did apply a vignette filter or your lens has a vignette problem. You also applied a filter to flatten out the blacks. Don't do that. Buyers can apply those filters easily, but they can't recover your edits if they need.

Look at the histogram, there is a clean cut off in the blacks area:

There is also strong chromatic aberration visible:

1161: Besides that nothing is in focus, you really face an IP issue here. You can photograph porcelain figures, but as they are the main subject and not only a decorative element somewhere on a commode, you will need a property release. You would also need a property release if it is a side element but custom-made art. And to add, the whole IP is soft science and Adobe tends to be on the secure side, so you may get an IP violation refusal, even when there is none, just because there could be one.

4185: Sensor spots as shown here:

(there are many more!)

You will need to stamp them out. Easy, but it's a nuisance. You will need to clean your sensor!

Composition: piece of paper at the right.

IP violation:

The 2nd image is blurry.  Almost nothing is in proper focus.  You need to work on depth of field.  

I suspect too that you will have trouble with intellectual property.  You need written permission from the porcelain artist/owner to use their artwork commercially.  While this may look antique, I don't think it is. I'm guessing it's a 20th century knock-off made to look like antique European porcelain.  So it's a problem.

I'll let someone else comment on the building.
