Funneling? More like ''let's make it easy for the attacker so he doesn't have to use wallbreakers''. Funneling can be great for lower level town halls, on TH9 you really shouldn't just open your walls and put some traps in it. And it's a farming base, your mortars really need more cover. They're very important against barch etc. Also vulnerable to giant healer because of the exposed AD. Sorry for being so negative, I know you put a lot of work in it and it looks pretty neat but I just don't think it's that great.
