you have been lucky to have been attacked by players who couldn't make most out of the raids. but believe me there are elemental mistakes in this base.
As many have pointed out, this base can easily be 3 starred using Barch or BAM.
Suggestions
1. Try to add funnels,
2. use wiz tower - mortar combo
3. Attacks from any side can allow attacker to get through to most of your storages. The storages need to be separated.
4. Trap placement can be improved




defenses won 7->11
