At the risk of being hated and knowing full well that "nobody likes a critic", the reality is that without the critical eye, art does not get improved or refined.

It's no simple task to avoid the "Uncanny Valley", and much moreso when you want something to look real, or realistic....
-- I like the archer because you can tell that she's definitely not a man in drag. Obviously you don't want them Evony-sized, but accenting the curves and/or muscles may help. Fitness models may be your best bet to model after...
-- Overly feminine facial features (aka doll-like) are great for cartoons but end up in uncanny valley for realistic art. The reality is that almost everyone has a mixture of masculine and feminine (facial) features, and the "hottest" models have slightly more on the masculine while the "cute" are on the feminine side.
-- Where are the blemishes? (uniformly super-fair skin but no freckles?? tans, dirt, scars, bloodstains? etc).

Hope this helps. I love them so far!
