Please do not design the females to look like the females in Dragon Age Inquisition. The females in DAI were designed horribly and is one of the main reasons I got a refund for that game.
I suggest modeling your females with your own unique style or use Witcher 3 females as inspiration. CDProjectRED is an excellent example of designing females that are not only diverse in their appreance, but are also attractive and non-attractive.
For the record I've never had any problems with how the females were designed in Fallout 3 & Fallout New Vegas.
I'm a huge fan of Fallout 3 and am looking forward to Fallout 4 a great deal. Thank you for hearing my words.
