Back for awhile. I currently have no ideas and certainly don't feel creating any designs myself for a fakemon to scratch. I wouldn't mind some ideas suddenly appearing in my PM inbox, if you know what I mean, people.
Relicanth is one of those Pokémon that could use an evo, but simply doesn't possess much potential in its actual design. That's a problem with a lot of fakemon concepts. As an individual sprite, you did a decent job aside from the flaw Tauros mentioned, but I don't like complete species changes in fakemon. No Pokémon based off of real animals ever change species in evo lines. Coelocanth to swordfish just doesn't work very well, however it was one of the only things you could do to make the evo look different. In the future, you might try Pokés with a bit more potential. All in all, good job.
