Yes. Looks good! I can see what you're doing with your design and it's headed in a good direction. I get the feeling of joy in Nature. You're filling the space with variety. All good.
You may at some point want to begin also working on your brush control as well so you have more variations in your 'bag of tricks'.
Here's yet another idea to add to what you're already managing. I believe a strategy wherein you think in terms of large masses of shape and related color and values that you subdivide will help you get a handle on a whole bunch of different compositional ideas. It will simplify your strategy. And then when you have your large areas placed, you can then go in and add some articulation and details and thus bring them into a fullness.
Here are some compositions that are very clear. They're doing different types of paintings than you are here. But it may help you see how the space of the canvas can be divided up -- for the sake of discussion and an illustration of what might be something to consider.
There are a lot of things happening and I don't want to overwhelm you with this and that. But looking at paintings and lingering and wandering through them is pleasing as a viewer. And as a painter, the artists are speaking to you about what they are doing and how they are achieving the things they want you to see. Notice the areas within the painting. See only that.
Try not to look at the details right away. And then, once you get the full impact of the setting, you can then begin to break it down into details.
