The whole image reads as very noisy because you have almost no sections that aren't covered by a 50% dither pattern. Instead of using a dither pattern to create "detail", use shapes that might actually be created by the details. Leaf clumps, maybe some individual leaves, etc. You shouldn't draw every single detail, but suggesting a few details would look more "right" than a non-descript pattern.
I tried using your tips on something else and it looks better ^^
