Finished working on my Mer-Man. Gave him a trident and some extra swappable parts. Got a Filmation head sculpt, unfortunately the LOP chestpiece restricted head movement so I had to get a cheap vintage(?) one off ebay. It's hard to tell but I used a toothbrush to flick a color shift paint on him to mimic a scaley look. Didn't quite work out like I wanted, but I'm happy.
