The design isn't bad; however I'm not the best on design for bases TH 6 and below so I can't really give great advice on that.
It looks pretty rushed (especially the traps, air defense, mortar, and collectors; wiz towers as well). That said you're not too far into the game; make sure you fully max TH 6 before upgrading TH: to fill the grave you started digging so to speak. I also noticed you have two builders and 10 gems; I'm not sure what you spent all those gems on but until you have 5 builders you don't want to spend on ANYTHING else, except maybe the collector boost events: while the extra builders may not seem useful right now, they'll be a huge help soon.
