...further minor changes might help suggest the sea theme...
Comms could use semaphore, make use of correct naval flags on units maybe.
Clamshell beltbuckles/shoe clasps might be easy to model?
Vehicles/robots/warmachines to have flotation tanks/rudders/propellors?
Seaplants might make for nice freehand cloak edging, seaweed rather than ivy?
There's that recent GW Dark-Eldf character figure with an octopus helmet that's a nice design.
My brain marches on but I realise I don't know what a Warmachine army looks like, is it those Warjack Dreadnaught things?
Perhaps someone else will chime in with something more useful?
Cheers, B.
PS Littlest Mermaid tattoos on bare arms? There's a nice nude one by J.M. Linsner (Dawn) knocking about that was a special in a card set years ago if you want to search for reference without hitting a Disney site
