Nice job there, but I`m not a fan tbh.
I like the idea, don`t get me wrong, it just doesn`t look quite right imho. :O
If I may make a suggestion?
If you filled in the screw holes (or just painted the screws red) & smoothed it to the rear panel & bumper, then extended it to the skirt & splitter, it`d look right, but atm, with the gaps to the standard kit, it looks too much like the red chavvy-kitted corsa that I pass every morning on the way to work!
Nice effort though, but with abit of tweaking, it`d look spot on imo.
Of course it`s your car, & your tastes are your own, but abit of `constructive critisism` never hurt anyone.
