Rejected of Quality Issues. What the exact reason?

Some photos have a shallow depth of field, try shooting them using the (Focus stacking) 

Were all these rejected for Technical Issues?  I ask because I see some potential property violations. 

The pad of paper has a design on it.  It is die cut in the shape of cat's head. Did you create that design yourself or did you buy it that way from a store?  The manufacturer of retail products may have issues with their product being used commercially.

Ditto for the baby's sports shoe.  Big name shoes & markings are protected by design patents.

065, 045, and 016 are depth of field related I suspect.  I think the depth of field is too shallow.

The cut out on 052 could use some smoothing.  The color tone of some of the finger creases also appear unnatural.

I'm genuinely unsure about 187.  The skin tones could use some adjustments, but I wonder if that's the reason.
