I’m normally a firm believer in sedans looking best in neutral colors/shades, but that green really does look good. Regarding the spoiler/wing, I personally think it should be one or the other. Both looks a little busy, unless the trunk spoiler you want is low profile
I think the conversion on that color would be soo unique. Dope choice juice! Have to hate a bit on those bar cut outs, I feel you have potential to do clean work, this just based off your style choices. Keep it up. 👍🏾
