A quick edit approaches!
Mine ->
<- Yours
First off, as other guys already said, banding is bad! No excuses.
The thing below mine is a comparison showing non-banded (mine) and banded (you's). Since I'm lazy, the arrow (that you can only see when zoomed in) is facing the wrong way, and the crops are only at 1x so they're kind of hard to see. In case you didn't know though, this forum has a zoom function so you can click on an image to zoom, and ctrl+click to unzoom.
Next up! your indent is shaded wrong. Mine ain't the best way of doing it, but on an indent, while one side receives less sunlight, the opposing side will receive
more, so yours, which is shaded all the way around, is... well, wrong.
