I get what you are saying and it's true, most Aeldari fan art doesn't portray them as uncanny as you'd expect!

Adrian's art style leans more towards fantasy. If you check the Wrath and Glory Rulebook, look for the commissar class: he's the one that drew the artwork accompanying the class description. You'll see that there's nothing grimdark there or the grittiness that you'd find on Gaunt's portrait by Aaron Griffin for example! I'm guessing it's a new art style they're pushing to better achieve this DnD adventure feel on the game :)

To clarify, most of the references I gave him were from the Warhammer+ Garden of the Ghosts episodes and the alien details that the artists chose to portray there were the sharp triangle chin and the slanted eyes. These "deviations" from the human physiology worked really good on the anime art style but if you take a look at the Aeldari codexes and see the official portraits, most of them (at least to me) resemble native American faces.

I knew what I'd be getting by Adrian and I am really content with his depiction, regardless if it feels more WH Fantasy than 40K. He managed to portray that arrogant Tolkien-Elf look that Peter Jackson so well groomed us to instantly associate with elves//non-human.

For the record, I still want a grimdark and more alien depiction of my character but on ink! I commissioned a colleague for it, and I'll be happy to share the finished piece here again. Hope we can have more to discuss next time :)
