"robb" ...
hello,
This is the my 1st SMT pcb etching project board.

Is there anything horribly wrong with the layout of the
components and/or traces ?

Any advice on how to improve or fix the problems with the
layout/design etc... ?

I assume it will not be plated through. In that case make the connection
points for external wiring as big as you can (or anchor them with extra wide
traces). If not, the mechanical force from the wires will break the traces
loose.

Guess: continuity tester?
