It is a budget setup

Setup Comments
First thing I'd suggest is upgrading that desk, get a bigger one, that's also wooden. Clean your area, and tif you can try to get a monitor, a good one (100~) and then, connect your laptop to the monitor, and in time try to save up for a gaming pc you can get a decent one at $500~ and it will help you a lot, cable management, a lot of potential. I like it!
