1. Blown out spot at the base of the waterfall has no detail
2. Overexposed highlights and underexposed shadows. The swan does not appear to be in sharp focus
3. If you zoom in to 100%+ you'll see that butterfly is not in sharp focus
4. Underexposed shadows and chromatic aberration
Thank you, Jill! I appreciate your input!
What @Jill_C said.
Depth of Field is important in Stock photography.
Do you use a tripod?
Most of the time, I do not use a tripod because I take a lot of pics while I'm hiking and don't usually carry one with me.
Thank you for your input!
