Things that I like about your Inquisitors is that they don't have huge freaky eyes however don't use too much makeup and try to keep eyelashes color according to your hair color or just little darker then your hair color it is just so off seeing light haired person with ultra black eyelashes.So far I liked most how you did Natia. Also other thing that I noticed is that you have your mouths too low try to make them higher.But like for Natia 
Yeah, I generally go for realistically-sized eyes for my Inquisitors, not anime-style eyes.
As for the eyelashes, it looks normal to me. I mean, I have light hair irl, but my eyelashes are black. But, I guess I'll try going for making the eyelashes closer to the color of my Inquisitors' hair.
Only about half of my Inquisitors have make-up on them, but I get what you're saying. tbh, with Lyna, I decided to go a little heavier on the make-up in DA:O because I usually don't bother with it beyond minor touch-ups, so that's why she has more make-up than my other Inquisitors. I did kind of use make-up on Malika and Lin'Mi when I probably shouldn't have (more-so in Malika's case), but I'm usually better when it comes to make-up.
And as for the mouths, after going back to look at them, I do see what you're saying. I do tend to make the noses kind of short, so that could have an effect on how the mouth-positioning looks, but I'm not entirely sure.
Either way, that's for the advice!
