I love Doctor Who, but you can't pretend that it's got some kind of patent on skeleton astronauts. You may as well say that skeletons themselves are off-limits because of Castlevania or something. Skeleton Mirror is as original an idea as any other. It's totally cool, the art is fantastic (please add more!), and it would be a super fun addition to Starbound.
buuuut it iiiiiiiiisn't what if you were a skeleton astronaut? you wouldnt say you were copyrighted. this art isnt using the vasta nerada at all, its a mirror that transports skeletons with space suits on. i do love doctor who tho. whovian forever
I think doctor who also did a comic where there was an evil mirror that summoned evil stuff, but pretty much everything has been done in some form or another.
If you see the "orignal idea" rule like that you'd have to change almost every single entry for this contest. No giant worms, no jellyfish, no birds, no bats in any form (surely some jrpg had them before no matter what kind of bat it is), no robots, etc. You get what I mean.
Cliffracer, Mercurypelt, and Lazar, you are all correct. I was just pointing it out. I realize the way I started the post had a misintended tone to it. Once again, very nice art.
