Seeing the info on f stop and shutter combo, I can see limited depth of field and not optimum clarity choice; as maybe 5.6-8. Also, slow shutter speeds in available light. I do not believe these are supported by a tripod either. General public would be pleased.
If there isn't available light- that's what you get in nature. These may be a little staged but not to the degree where reflectors and other light sources would have been used to optimize.
