Is this instrument primarily used as a sound mangler, or do you have other intentions/goals for it, as well?
Just for future consideration, I make copies of my racks before posting a comment. That way, even if you play around with the rack later, the version associated with the comment will stay the same. Makes it easier to comment on your rack without providing obsolete advise.
Speaking of which, I typed the below out before seeing that you actually did add a number of utilities. That being said, I'll say it anyways and risk being a dead-horse beater. Utilties. It's hard to understand how cool and useful they are until you play around with them and see what they can do. To that end, I highly recommend the micro Ornaments & Crime (particualy with the Hemisphere firmware loaded). Really gives you a great selection of utility options in only a few hp and only a bit of menu diving. Getting one really opened up my rack when I was just starting. Once you identify what type of utilities you use frequently, you can buy a dedicated module. I see that you have the 3xMIA and 3xMIX (I love the 3XMIA, just wish it had a detent at 0), but as you spend time with the hobby, you'll see what other options there are and what they can do.
Next, lets talk signal flow. You've got two cases, are they side by side or on top of each other? How do you want the signal to travel around the system? Some people feel it doesn't matter (since it's modular after all), but I'm a visual person and like to have my signal go generally left to right /up to down. Thinking about how the signal will move through your system may help you realize where there are gaps in function.
Hope some of my rambles are useful. Anyways, good luck!
