Various line art used from  howling-valley-creations and one I don't know where it came from, just a random one I found for an otter tail, but anyway, the tail is bent and it shouldn't be bent like that. Much less bend and I don't feel like fixing it now.

Twitch Otyolf, originally planned to be a mix of an otter, coyote and wolf, but now he's showing much more otter than anything.

Pitch black otter with neon green paw pads, matte neon green claws, black paws, and webbed fingers.
His tail is black on the bottom half, 7 color rainbow topped.
His head is pitch black with charcoal black inner ear fur and nose, light green eyes. He's got 3 whiskers on each side of his muzzle, pink tongue, and the little row of teeth on his bottom jaw.

I'm uploading this so I can link  sassypupcreations for a reference, since she's hopefully going to be taking over my fursuit commission, since my previous commissioner bailed.
