i'm not much of a graphic designer, but i thought it'd be neat to workshop an idea for a poketherian symbol of some kind! it's not super fancy, but i think it gets the idea across ^^
i'm also still thinking about other ways to do the symbol - as much as i love the iconography of the pokeball, it's also a man-made object and a bit human-centric, so it'd be interesting to find something that's a little more oriented towards pokemon themselves instead!
That being how to make a Pokémon therian symbol that doesn't incorporate the manmade Poké Ball. I thought maybe the Arceus symbol might be a good substitute, so I threw this together quickly to see if it might work. I think it's a little too visually busy compared to the first symbol, but it was still fun to try and incorporate the two into a single design!
EDIT: Added those lil gem hole thingies on the ring spikes, I think it's a lot more obvious what it's supposed to be now :P
