i like the direction you are going with the tail. if you finish that wing & cap setup, i would add metal to the bumper to fill in gaps. have you though about recessing the inside of your wing/end cap so it lines up with the tail light panel like the stock ones do? that might look slick and break up some of the the flat look on the side and top of the tail light. just a thought
btw i wish my garage was as clean as yours !
