Much better but again you don't have much clearence between base and lower gantry so just becareful you don't limit your options.
What size are those rails.? They must be 30mm if profile is 40 and 30mm is massive OTT.
You havent shown a view with how the bearing plates fit with regards gantry cross piece, don't get caught out with common Gotcha of not beaing able to get to bearing bolts.!!
With you have such short travel distance then I change my statement about having Z rails on front plate. With this short stubby design you'll be better with them on the rear plate as you will hardly ever extend below the bottom of the rear plate when spindle is attached. In this case you'll need to go up more than down for tool clearence so you may need longer rear plate.
I suggest you continue with design and draw in the rest of the Z axis with spinlde to get an idea of what cut travel you'll have available.
