Looks very nice but if you want a stiff machine use a raised X axis design instead of long gantry sides.
Also on the Z axis you've gone for the tuning fork layout. Look at the layouts where the carriages are fixed on the Y axis and the rails are on the Z plate.

Zeeflyboy, it is an art work! Where do you download the ballscrew and slide 3d model？I would like to design my own one.
