Thoughts... yes let's start a new thread for this, link it here.
Besides these pulls looking AWESOME! I would suggest the following....
Assuming the corrugated type bumps on the flat sections is where the air is drawn through, to make the trim line cleaner and more identifiable you might want to either extend the molds with some type of secondary edge (trim line) or elevate them so that the corrugated section does not extend beyond the, to be, trim section. Hope I'm being clear here.
