One such problem is this:
You have a burnt-out area and you can see artifacts.
This won't be any good printed or when enlarged. The overall picture quality isn't good.
Clipped highlights, lack of detail in the shadow and lack of sharp focus on the front leaf which should be the focal point.
To be honest, it's not a visually compelling photo. I'm not sure who would buy it or what they could use it for commercially.
