[Suggestion Doodle] Call of the Blood Moon (Patreon)

Someone has been patiently awaiting a Red Merman~ (specifically a buff, pale one!), and so I thought for a bit, how can I best compliment those themes.... blood moon actually wasn't my first idea, but when it came to me I was fully sold on it XD
I hope it satisfies >^<

This might be one I come back to fuller render down the line too cause I'm actually really proud of this composition ngl >///>
