If possible I'll be going with Dalish female elf as always (apart from Hawke for obvious reasons). Personally I have trouble to play male characters, I don't really 'click' with them and it's neither about romance, nor dressing options, cannot pinpoint the reason really.
Most likely rogue as always (with exception of Hawke again... because I originally hated the combat system and thought that running as mage will make it easier).
I like to make my characters divers appearances, history, motivations and personality traits, but apart from the appearance the rest is getting build during the play.
Kinda quirky but I use humanphenotypes.net website for identifying a general form for my characters. My Warden was likely someone from Malid group, my Warden Commander Proto Nordid group, Hawke - Tungid group and Inquisitor - Polynesid group.
I'll likely go with some group from America this time.
