Looks good Tom. Are the gantry sides aluminium profile or lots of steel box sections joined together? Needs to be steel to get maximum stiffness on this critical area.
Thanks

Looks good, I'd beef up the bed as it looks weak compared to the rest of your machine 😊

The other weak link will be the spindle clamp. Needs more clamping area or clamp top/bottom.

You have the rails bolted to the table, a very good start.
Second picture you go wrong. Your mind is stuck in 2D and it has put a terrible overhang on the router to gantry connection and compelled you to move the bed bearings out from under the gantry creating the awful L shape.
There is no reason why the Z axis slides have to clear the router head, they can go either side of it.
Do it again and think overhangs, think 3D
