Nice work! You made a lot of great design choices.
+1 to those that recommend upgrading your extrusions and motor mount on future iterations. The rigidity is well worth it.
If you are ever deciding between belts and ballscrews, I recommend ballscrews. It is worth the extra $$.
For the milling of aluminum, I suggest adding a compressed air nozzle. It will make a huge difference in milling AL. Also, some of the new bits are fantastic at hogging out aluminum. For reference see pic at https://drive.google.com/file/d/1BWvOOwmaQljwhdBzYNvilYDKdsy...

We built our own 5-axis CNC too, to do large envelope parts trimming. It looks like Frankenstein, but works pretty well. See a pic at https://drive.google.com/file/d/0Bydp4fsq-EhtUndOTlZTcU1fTEU.... We use it to trim the chassis parts for our baby car seats at https://kioma.us
Keep on building!
