first time making something in blender

I've wanted to learn how to do stuff in blender for a while now so I decided to try to make something! It's just a golf ball in grass and the materials are made with nodes. Here is the render: I used 2 youtube videos as reference: Mini what?? (the golf ball) and Also grass! (the grass) by Default Cube on youtube.
