Welcome (officially) to BYOAC!
Looks like a promising start. Are all the bondo marks from screwing the furring's from the outside? Is there any reason you didn't go from the inside?
Either way, looking good! Any specific superhero you are going with?
My fist arcade attempt is in my signature, as you can tell, I have as soft spot for The Punisher.
Look forward to your thread, I too, am a novice woodworker.....aka, hacker...lol
