that last one looks crooked. i see how it's following the door sill edge, but the door sill is somewhat concealed, so my eyes compare the decal to the hard edge of the rocker panels.
the car is just too curvy for straight-edge decals!
you could consider something like this in a matte finished clear to add visual texture without being as obnoxious
or this highlights the natural curve, again, my preference would be a matte finish decal that would keep with the body color, but add visual flair. but it looks very hemi-ish to me. i immediately think of the dodge charger.
the upper version in this one highlights the forward curve
i've also considered something like this in silver just ahead of the rear wheels to break up the large surface area of the sides.
