Yeah I totally agree, no turn signals is an accident waiting to happen. Besides, the next cop that sees you and feels like being an asshole will give you a ticket for that-- cops LOVE to hand out tickets for non-functioning or broken headlights/taillights, turn signals, and brake lights, especially if it was due to a modification. On top of that ticket you'll most likely get a court order to remove the turn signal obstruction-- and if you can't cleanly get that paint off it might involve getting replacement tail lights.
The paint looks good, but if you're going to paint anything in the future I'd recommend disassembling it first and painting it in a dust free and ventilated area. That way you won't get dust or particles in any of your coats and you'll avoid accidental overspray onto the car body. Even with masking off, you'd be amazed how far overspray particles can travel.
