Please forgive me the audacity of having done a workshop on this fabulous image with which I congratulate you.
I moved the two rhino closer together as I thought there was a bit much space between them. The white chunks of calcrete bottom foreground also were a bit distracting. I tried to decrease the overexposure on the back of the smaller one and played around with brightness and contrast which resulted in slight adjustment. I hope it is acceptable to you.
