This looks fine.  Some suggestions/comments though:

- I wouldn't personally bother with a separate /usr.  You could
  move this onto the Root LV and remove the Usr LV.
- The size of the Root LV is more than plenty for /+/usr
  combined for all but the biggest installs.
- The size of /home is very big.  Not really a problem if you
  need that much space right away, but I'd personally have made
  it about ten times as small and left the remaining space
  unallocated until I was sure what I needed it for.

- If you made the tmp LV into swap space so that you had around
  18GiB swap total, you could then mount a tmpfs on /tmp which
  could potentially be much faster, depending upon the amount of
  memory in the system.  Or just remove it and extend the tmp LV
  --now that you're on LVM you have the power to play around with
  this!  See /etc/default/tmpfs.
