a couple things i would like to see. please do not be offended, as this is offered as a safety tip.
i noticed a couple of wires going through drilled holes. those need grommets to protect the wire insulation.
also, i like to see wire bundles going through body cavities, like the kick panel area shown, protected by something [even that GM split plastic ridged stuff] so as to keep the bundle safe from rubbing on the edges of the cavity openings.
