I see Wynn as a Chakwas inspired doctor role considering she’s a different kind of healer who shares a mutual love of fine spirits. (Wynn can be gifted wine and talks to Oghren about her knowledge of ale in Origins).
This makes sense and the artwork is as mindblowingly awesome as every piece you do, but considering that Wynne is a magic user I have to agree with Woodclaw that Wynne would translate better into a sentinel rather than "another Dr Chakwas". But then again, Wynne could very well be a sentinel or biotic in this picture without showing it.
If I just made every single mage into another standard biotic soldier then it'd be a pretty dull line up. Don't see why she'd be a sentinel either when she has no traits suggesting she's skilled with tech.
Perfect !! I really love Dr Chakwas and Wynn characters. Bioware did really good job with them : it is rare to have charismatic and elderly female characters in video games, but I think both are just perfect women.
