I think it can be helped a bit by more dense tree placement, it's all a bit too sparse righ now to feel like a jungle. If it were me I'd probably try to reduce the amount of path types, or atleast the bits with random brick path. I think it makes it feel way too busy.
I agree with the stuff Gforce said, I'd also try and work in some darker greens into your foliage mix, right now the light green stuff is overwhelming.
The arrows on the plates I liked.
Sincerely anxious to see your park when ready
