My first go at making a CNC router

That's ok for the broad strokes of the design but it's the little details that will bite and you don't show any.! You also need to ask your self if copying someone else's Bad complicated design is worth the trouble.?

There are easier simpler designs that will work just as well and be stronger. For instance frame with high sides with simple beam gantry sat directly on rails is much stiffer than high gantry sides and far less complicated.

Word of warning if this is your first machine.? It's common mistake to think that building large machine is just as easy smaller machine. While in essence it appears just matter of scale, which it is to some degree, problems lie in that the obsticles to over come, like rail alignment etc scale upto match so if you've no expereince then expect some serious hair pulling.!!

Unless you really need large machine I advise to cut your teeth on something smaller.
