New th9 with 4 mortars

I admit normally I just look up a base online and find one I'm comfortable with and that satisfies my OCD and need for symmetrical layout. But after the 4th mortar came out I haven't found hardly anybody posting th9 bases online with 4 mortars. So I decided to try and create my own th9 farming base. This is for gold defense. I don't care about elixir. Now this is my first base I've created and actually been serious about it and I'm not anywhere near the best. But I'm actually trying to create a base now. So what do u think and ANY advice would be welcomed. https://docs.google.com/file/d/0Bw9b...p=docslist_api

Hopefully I've done the link right. This my first time

Also plz just critique the layout not the fact that it looks under developed. I rushed long ago and just got back on and startEd playing seriously again.

Your DE is exposed maybe switch with barb king.
