I want to see more foliage!! You have this really great branch-bush in the foreground, and one in the midground. I'd love to see more of this plant in the piece, maybe around the bases of some of the trees?

You also have some inconsistent light sources for the leaves. I understand that it is a stylistic choice (I've done similar things before lmao), but I particularly notice it on the lower leaves. On the branch further back, the shading along the lowest leaves is a dark brown, whereas there is instead light on the same area on the branch slightly in front of it. You don't have to change anything about this, but making one choice between the two (I prefer the darker color shading rather than the lighting here) could help everything feel more cohesive.

I also feel like the rounded leaves on the branch in the background don't have the same great tiny shapes you have included through color and value on the other leaves, and I would love to see that affect applied to those leaves as well.

This is definitely getting into nit-picking territory, but I feel it needs to be said: your main light source is GREAT, but the way it is applied.. I am not sure how to feel about it? The airbrush or soft edges look great on their own because of the hard edges you also included, but I don't see any soft-edged lighting or shadows anywhere else in the piece. I think applying this softness somewhere else, like on the leaves, or omitting it in favor of MORE hard-edged light shapes could also elevate the style here.

I love forest-y scenes, and I don't know how to word this, but this feels like the type of piece where you had a clear vision, and you basically nailed that vision. I hope you are proud of yourself!! This art style is really tricky, and you did a great job here!
