You should start by importing a super simple base mesh, that way all your major proportions are already correct. It's not cheating because it's what every professional does.
I'm aware that using a basemesh is the standard, however, I felt that doing it from scratch at least once would give me more practice. Like how you should set up a gamemode manually in tf2 before using booj library
Also I can feel more badass knowing I started with a goddamn sphere.
I'm still figuring out when to use which tool, and hotkeys for the most part...
