I would like to add more voxel drawn ships to my game as unlockable extras but I wondered what the legal position is with copyright of space ships from other media. For example, I drew the model below using Magica but it bares a likeness to another space ship from a sci-fi movie series.
Since I produced the model myself - all be it inspired by another - do I need to obtain a license? I imagine getting a license as a one-man indie developer is impossible or incredibly costly, so is there another way?
I've tried googling this but don't seem to be able to find a conclusive answer.
Thanks in advance.
