Guys what should I upgrade next. Im really not sure

For the past week or so Ive been upgrading my walls with my Gold and with the excess Elixir from upgrading troops, I've been upgrading walls to level 9.

AQ going onto 7
BK 7

As you see I have basically max Gold and max Elixir so I was thinking of gymming my queen and completely putting all my Gold into walls and some Elixir in to level 9 walls and then re upgrading my AQ.

Can anyone plz tell me what I should do next in order...
Like If it would be possible what should be the next 10, 15 or 20 things I should upgrade since I have 5 builders and I do farm a lot.

Thanks for your input guys!
