Looks pretty balanced overall from a functionality standpoint, but it does seem like there are a ton of mults for a rack of this size. If you use them, more power to you, it's just the one thing that stuck out to me.
As (I'm guessing) other users will chime in to say, you might stand to add a couple of utilities in place of two of the mults (if they're not crucial to your sound). Something like a quad switch or precision adder might be worth looking into.
Best of luck and hopefully the more seasoned users will chip in with more informed suggestions!
