I think it's a bit of a shame how Vivec's appearance changed in the games after Morrowind. I always got a sort of uncanny vibe from his Morrrowind appearance, like he's staring straight into you, that I feel like wasn't captured as well in his later appearances. I picture him with a round face (for a mer), and huge eyes and ears. Just absolutely big-ass orbits and ears big enough to move like a cat's.
The first set is from February (you can thank it for giving me hand/wrist pain), and so I'm not keen on finishing it, but liked it enough to post it anyway.
