In need of Townhall 9 Farming Base Advice

Hey Guys,

I just created a new design for townhall 9 farming base. Please go ahead and give me some advice. This is my first base design and i probably made a lot of mistakes. Thanks. The place on the left where the wall is missing next to the cannon is an accident. My fat fingers must have dragged it before i took the screenshot :eek:. To my knowledge I have not copied anyone and just winged it. Please do let me know if it has already been done. I don't want to plagiarize.

I think its a solid base :D nice job.
