A while back there was a discussion here about how crosstalk in rectilinear traces (I think there’s a term for this but this is how I think of them) are becoming a bit of a problem and that more organic looking lines (not unlike these) can help.
Audio people are notorious for detecting noise. That hand drawn circuit might be less artistic and more practical than you’d expect.
I designed a couple of small PCBs using crepe tape and etch-resist transfers. Sometimes this was directly onto the copper, but usually it was onto acetate to be used with UV sensitive etch-resist.
