Looks like you had some good fun putting that together!
Nice work on the textures in the first shot; it’s not all green grass. What stood out for me was the use of the brown muddy looking texture where the crowds of people had trodden down the grass between the different attractions.
I have one tip regarding your foliage. Try adding some shadows underneath the trees and shrubs. There are some ready made ones on the DLS, but you can also use textures. A good texture to use is USA Forest 3 <kuid:-1:100798>. Use the minimum radius (to get the smallest “shadow” spread), and maximum scale (so that the USA tree image isn’t obvious). Go in with a vertical view over the center of each tree and give a (very!) quick LMB click to get a faint burst of texture on top of the previous texture layer. The same USA Forest “shadow” works equally effectively over other surfaces, such as gravel or concrete, provided it is given a light application, because it will blend nicely with the previous texture.
When applied, move back and admire the results. As well as having an acceptable shadow it will also give the illusion of the tree/bush being anchored to the ground, rather than a floating appearance.
