I decided to try and make a mountain range, I didn't have any real reference and was just going off the top of my head, this project really made my computer tank so sadly couldn't do much more to improve the render due to it taking so long to make just one change but maybe in the future I do something like this again, hopefully with a better PC.
Here is a screen capture of the mountains combined which shows how I utilized depth and how I set up my scene
I started off Blocking my scene with basic primative shapes to get the rough shape and design of my mountain range where I next joint them together and started sculpting
