I must say you have put in a lot of effort and money to make it what it is. But since it would be difficult to throw away whatever you have done to your car. here are some suggestions.
Remove the sticker from the tail lights and get LED's on.
Spoiler is Ok if you wanna keep it otherwise remove it and get a LIP spoiler on it.
Bumper is good.
The grille is a bit overdone but to make it look acceptable paint it to matte black.
sideskirts are ok.
Change the alloys if possible ot get them painted all black.
more suggestions will be appreciated from fellow members.
