Looks a little simple, also I think that its shoulders are too wide for the mocs proportions. Anyway good attempt at the custom limbs and torso, however looks a bit boring to me.
It’s legs are giving me a Storm Beast PTSD…
Anyway, I would change the lower legs and try to armor the back more. Other than that, it’s not bad, not bad at all.
Looks a little strange, personally I’m getting more of a ‘water beast’ vibe than a hero. The leg design for example feels very much like the 2016 summer beasts.
