Memnon / Atlantean admiral + character design guide

Hey guys,

Memnon is Castor's adversary in the story of Bellovesus from my unKnown world of Ída (artbook)

Memnon is also the commander of the Atlantean expeditionary army against which Castor fought in the Battle for Argos.

In gallery you can see new episode about him. It is small guide on how to approach character design, with a bit of book lore and inspiration.

Here are some concept art as a visualization of this character.

UPDATE:
so I came back to Memnon illustration and little bit redesign him based other sketches and on feedbacks from my YT subscribers.
Hope you like it this design. Personaly I think new version looks cooler and badass.

Also I have feeling this design is more fantasy then my rest of my "historical" warriors from unKnown world.

What do you think?
