Don't be fooled by his humility. Modred IS an expert. Great advice.
This painting is a departure for you and there is a whole school of painters who focus on pattern and the decorative simplification of shapes as representations. It's quite common in illustrations and folk art. You're somewhere between natural and stylized with this one.
My personal taste also goes toward the more natural as I think Modred is pointing toward. And you seem to have been favoring the natural. But I just wanted to comment for you to observe the fork in the road that heads toward 2 different looks and how some painters might go toward filling a picture in a decorative way with the simplified idea of trees etc.
Anyway, great stuff. I love how you're observing details putting some nice finish in. Possibly as you step back to an earlier stage in the painting, that's where the vocabulary of how to construct a tree and so forth would come into play. And naturally that would then dictate how much detail would be necessary to include and how much could be implied by your earlier placed marks.
Go man go!
