The biggest problem with this base is that, like most TH7 bases, It doesn't cover your storages well. Your dark elixir is completely exposed, and your gold can be stolen easily by attacking from the left and right. The wizard towers are practically irrelevant in this design as well.
Nice junctions, though. Keep up the good ideas, and keep working on it. It took me 6 weeks to perfect my TH7 design.
