Some (nice) renders

I’m quite new at blender, I’ve made a car before (submitted it,too). So these are some of my first renders. I would like some crits, though. All fully made and rendered in blender.

The first one is an American beach with a nice boulevard. :stuck_out_tongue:
The second one is a waterfall I made with a tutorial.
The third one is a very bad render of grass, but I just wanted to post it.
