looks good bud, but I'd have plastic welded in a piece to the edge of the bumper to fill the gap you can see from above before doing all the paintwork.
Looks interesting and it's always cool to see people putting in efforts like these. If no ones done it, we'll never know how it looks. Personally, I'm not sure if the bumper matches the contour of the car. Maybe some p10 side skirts? The b13 is almost like a ef 4 door civic or the early 90s skinny boxy cars when the p10 added more body fat. Better then buyin those humongous fake fiberglass kits. Good effort!
