Looks great! I used to do a TON of the vinyl striping. The corners you did look very nice. I found the trick to doing those was to tape a can lid with the right radius in place and lay the tape down around it. Laying it down, instead of stretching it around the corner, kept it from lifting as it was trying to go back to it's natural state.
Thanks for posting, brought back a lot of memories! I couldn't tell you how many flame layouts I did with that stuff.
