Regarding load capacitors, as written in the PM, it doesn't have to be 18 pF. Pretty much any 27 MHz crystal/oscillator will do.

The schematic "connections" are all right, but as I didn't have that many components in my Altium library by the time I made the design, some components are only placed for the footprint. For example the 16MHz crystal seen on MAX7456, should be a 27 MHz etc.

All decoupling caps can be changed if you want. I just added a bunch of footprints to have the option.

Also, you can take a look at the integrated OSD for a bit different layout, DC-DC switching regulator, current-sensor, pressure sensor etc.
