Alright Phony, I like your one simple, so here is my advice on how to evolve it.
First P I broke down your letter structure, it is what you currently have.
Understanding how the blocks make your P is very important, I suggest doing all of your sketches like this, than erase the inside lines after. Second P shows how just extending some of the blocks a little bit adds some style. Third P adds a bend to one of the bricks. Fourth P shows changing the width of 2 of the bricks at a gradual pace.
I would recommend doing a evolution of each letter of your name separately, showing the building blocks. Then once your are comfortable with each letter, mold them together with some sort of flow, such as having a symmetric bend in the letters or whatever you can create.
Hope that helps
