Ignoring the fact that it was disingenuous anyway, perfectionism of this sort belies a lack of confidence. There is enough evidence, from the Beatles, to Motown, to Elton John, to Philip K Dick, and decades that cover the key times for comics (to mention just a few).. you're better off getting the ideas out there without fretting about smoothing the rough edges too much. And it's  a notion that doesn't even really work for an immediate, generally non-iterative medium like comics anyway. Just get the work out there.
