It's just a matter of trial and error, knowing witch facial features work together, turning the face a LOT to see it from all angles, and also start with him (or her) bald, since you should choose the hair to match the face, not the opposite. Doing this, the hair won't get in the way and you will get all the proportions right.
When I bought the game I sucked at making characters, they all looked pretty plain and basic, not to mention that from some angles they all looked weird, with noses twisted like they were broken, eyes that were sink way to deep into the skull, and jawlines that stand out way too much, making them really unnatural. Sure, some people have wide jawlines, but they feel harmonic with the rest of the facial features.
So yes, take your time in the CC, after all you will be with your char for more than 40 hours
. Believe me, I scrapped way to much characters before I started doing good looking ones.
Yes now he have the black emporium to fix them, but I if you use mods like me, the game freezes wen you try to use the mirror for some reason, that if it loads the black emporium at all (With Robyn the game freezes wen I try to enter the BE, with Askari wen I select the mirror, I can only fully use the emporium if I disable the mods).
That being said, you're in the right direction, your last char is very handsome 
Thanks for the encouraging words - they will be needed as I'm kind of forced to restart with Eoin *internal screaming* I've got the wrong world state loaded and if he's to be my headcanon there are some quite crucial elements I changed for Rabastan/Nìla pt so my headcanon play would be different..
I'm not far along the game - about ten hours in - but have to say I can't recall the last time I was as furious with myself. I'm not even sure I want to play now or if I should just get the sliders from BE or just completely remake him - both options seem kind of painful .__. And I was doing so well for it to be my first nightmare play through (now I'm not sure if I can be bothered)..
*bangs silly head against wall* I wish the world state you loaded came with the name of the ws and not just the timestamp...
Anyhow, thanks anyway... I kind of thought he was handsome too, though he was to be a little bit of an oddball of the House Trevelyan...
I really like how Halaslan looks. I can never get that hair to work for me when I'm in CC... And I also seem to struggle with making good looking green eyes.. Never really goes well with the skin tone and complexions I've picked.
@Khylian thats honestly one of the best looking male Lavellan I’ve yet to see
- jealous to infinity !
@hawkins437 Rilke reminds me a bit of Scout Harding… Like, she could be her younger sister or something. Not a bad thing at all… I love how you’ve managed to make her features quite petite but still made her quite true to what dwarves normally look. Great job !
And I think I've liked nearly every picture @Rascoth has posted on this topic since I joined 
Question, now that BE is available, have you guys used it to change your inquisitors look to go with the story or do you just use it for tweaks or if you want to change things up a little ? My plan with Eoin was to add more scars after the attack on Haven and was just wondering if anyone else does this...
