You probably don't want to pay the $500+ I'd ask for even the simpler ones.
Jokes aside making these need a lot of time work and patience. I'd really hate to re-make them. (I'm making a 2nd build of my Skyrim dragon and its SLOW) So basically they are not for sale. But the templates are available for free, so you can take a shot on building them.
Aww, but as a fan. It would be worth it, like seriously worth it. Now that you have mentioned that it isn't for sale. Asking wouldn't cost me anyways so how did were you able to make this? Used special equipment? Materials?r
