Ahhh!!! I love the third to last one! She’s like everything we described to a T! 
5th silver eyes
6th: seaweed green hair that’s wild and free-flowing!
7th comment: shirt and pants the color of the ocean and flip flops when they’re on land.
8th comment: Their personality is that of a vigilante who believes in justice! They can’t stand people who litter and want the power of Poseidon to rain down on those who contribute to oil dumping in open waters… If they just so happen to be that justice that’s fine by them.
9th comment: they have seashell earrings.
10th comment! They speak multiple languages. 
We need a new comment #1!
- Incarnation of Shiva (8 limbed humanoid)
2nd Comment: Uber Macho Man He Him
Here’s the collection of the 2nd character!
Summary
A non-binary merperson who goes by they/them pronouns with teal skin and deep purple (but faint) veins. When they blush, their skin turns to eggplant and anything that normally would tend towards pink (like lips) shifts from purple to frosted lavender due to water temperature. They have wild and free-flowing seaweed green hair and silver eyes, and wear a shirt and pants the color of the ocean along with flip flops when they’re on land. Their personality is that of a vigilante who believes in justice! They can’t stand people who litter and want the power of Poseidon to rain down on those who contribute to oil dumping in open waters… If they just so happen to be that justice then that’s fine by them. Aside from their seashell earrings another fun fact is that they speak multiple languages.
3rd comment!
skin color - a rich mocha color, probably taken care of with some nice smelling oils.
4th: Platinum Blonde with dark roots
5th comment: dark brown eyes
I love 3, 4. 5! I think the third looks the most gender neutral. Baby needs a name!
I’m sleeping now, but 6th comment: hairstyle - let’s do a single braid down the back.
- Grunge: leather jacket, work-worn jeans, plaid-flannel denim shirt somewhere (sometimes on, sometimes around waist), work boots, snow cap
8th comment: aloof towards strangers, loyal to loved ones
9th comment: accessory - let’s do a kingly scepter.
