Nice job. I always add shut offs to all my fixtures as I upgrade them or sometimes proactively. In my opinion they should be there as standard items. If you have a plumbing issue while travelling, you can isolate the problem and still have water.
If you truly want to see a rats nest, pull your power center out of its mounting. I warn you though it's not for the weak or the faint of heart...
