How good is my base?

These pictures are of my base and attacks. I keep being destroyed, so can anyone suggest changes or post a good base design. Constructive criticism is appreciated. I am using an army of barbs, archers and gobs(it was on the forums but I forgot who made it).

is it worth upgrading my barb king? I have heard it is not a good idea but I am not sure. Thanks in advance.

Kick out mines and pumps. If your active enough they don't need to be there.
Use those walls to segment the core
Centrallize the cc
Splash towers and air defence forming triangles
Layer the other buildings evenly around.
Or you could copy a base from the th7 design thread.

Edit: now that I see how much you lost your probably better kicking the th out of the base. When I was th7 I did a hybrid base but that's just me.
Also, you have a minimal amount of de so its not worth keeping the space in the center. And the bk was a no go for me. I didn't see that much improvement and its much easier at th8.

Here's the base design I used at TH7: http://clashofclansbuilder.com/plan/103344. I rarely got two starred and those that one starred me gave me a free shield by attacking my town hall. Sometimes they even tried attacking the town hall but got distracted and ended up with little resources and 0%
