The schematic is coming along nicely. On R2. the right side should connect to ground, not to CS_3V3.
The regulator data sheet has some notes about possible instability with output capacitors larger than 22uF. If that turns out to be an issue, you may need to drop that 47uF cap down to 10uF, so make sure the footprint you choose for the PCB can take either one.

I believe that the wiring of R2 is intentional. The LED will light only when the board is selected and the clock is high, doubly ensuring that the LED means board activity. It also lowers average LED current. The '245 has more than enough drive to sink the current. Kind of clever actually.
