How to go about practicing environments and perspective

[Setah]

Hi there! I'm doing a personal project at school right now, and it requires me to put at least 56 hours into practicing my basics when it comes to perspective and environments (. I'm a complete beginner when it comes to these two, so I thought I'd do some research on what practice is the most effective for what I want to learn. There is just so much to learn and it's a bit overwhelming, to be honest. Any advice on where to start?
