Oh, this is perfect for the sea elf campaign! By the way, did you take the texture of the elf archer from the seventh game?

A swordsman sailor would fit perfectly with the archer and hydromancer.
I think this unit is more necromantic because I use design elements of undead from Heroes 6.
Specifically, this is the scaled breastplate of a hero-mage and the bandages on the arms and legs (liches, vampires, and undead heroes in the sixth game are wrapped in bandages; it's a cool detail).
