Finished version 1 of the layout, apart from some minor quirks.
Added a charge pump fromt the regulated 5V to double the voltage to regulated 10V, for the gate driver.

I dont like this layout. It sucks. Areas to improve:

1. Looks super ugly
2. Doesnt have power connections
3. Doesnt have a continuous ground plane at all (really bad for signals)
4. Buck layout has heaps of vias which stops me from putting anything on the other side of it.
5. In engineering, do everything twice, because youll fix all the stupid mistakes you make using the power of foresight.
