6/10
Mae is adorable, but she looks like a lot of other dog characters I've seen. Nothing really stands out to me, but her palette is pretty nice. I like the pink. Since she's your fursona, you could possibly add something that reflects you more. And you probably wouldn't want to do this, but maybe even change her breed to something that isn't seen as often? I haven't seen a lot of corgis for example.
Those are just suggestions though! She's a nice character, just not really my speed.

Era?
Design and art are by me. I mostly made him with springhole generators and want to maybe make him look more interesting?
the shirt under his vest is supposed to be blue, but my monitor is messed up so it might look more gray than it's supposed to
Anyway, Era is a demon in disguise. He has dastardly plans to take over the world but is actually too afraid of failing to carry them out, so he's just that weird ageless guy who never goes grocery shopping and lives in a possibly-haunted mansion. The pendant (design subject to change) is tied to his life force, and if it's broken, bad things will happen. Mostly to him.
I don't know what to do for his demon form either. He's set in a modern time period
