Been working on this the past two weeks or so. It started out as a papercraft model, then I filled the inside with spray foam, coated the entire thing in resin, and then put a final coat of auto body filler on top of that. That was sanded down nice and smooth, painted, and finished with a slightly glossy sealer for protection.
It's extremely lightweight and durable, so it's perfect for a cosplay prop as well as a collector's item or decoration.
I'm pretty proud of how it came out, especially considering I've never done something like this before...and it's definitely not my last, I already have my next project planned.
I'm selling it on Etsy if anyone's interested in it. Check it out!
