Learning Blender to make a high quality render like that takes time. I have been using Blender for about three years and still don’t know how to use loads of features. If you want to learn Blender start by checking out some basic tutorials on YouTube, the once you know the basics try some more advanced ones. I would reccomend checking out my post in the best Blender resources thread for all of my recommendatios (The best Blender resources - #3 by Withers99)
