This base looks pretty good! You made it very well-rounded against most attacks. My only complaint is that the gold/elixir storages are pretty easily accessible, and most people could barch at least two of them since there is only 1 layer of walls protecting them. As a general rule, it's good to keep storages at least within the second layer of a base design.
Overall though, I like what you did- great job!
