I suggest studying layouts, not just look at them, but study them. Ask yourself "Why does this layout work?" It's certanly not just because it looks complex. In order to become better at layouts, you need to know why layouts work. Each layout serves a purpose, be it to purposely hide secrets (or in MP's case PUs), to lead you straight to the base, or to be as confusing as mind boggling possibly(not that it's a good design choice, mind you). Not giving the layout a role might damage it in the long run.
