Imoen is just too loveable a character to not have a romance for the PC, however one thing I have noticed is the lack of off LOVETALK PC initiated dialog.
If this is still in the works, I'd suggest adding options for flirts and maybe adding a few more optional quests, prehaps in relation her reaction to the strongholds? i.e: Theives Guild; Imoen= Theif/Mage
Or maybe a similar story to Jaheria's bandit encounter?
Also I'd think the interactions between the female bioware romances could do with just a bit more revising, say in the case where Imoen should drop the act of being just a 'sister' and actually try to pry the overburdened PC's attention more than usual; of course only when appropriate

As for Imoen's psych, I'd say its on the right track, to me she has always been more spontaneous to me than carefree.
(edwin ramble: That little mynx cheerful and stupid one minute, strange the next, of course not to my standards of intelligence, pathetic simians)
Anyways, I love the sweetness of Imoen's romance, and the more 'natural' the better I say

Keep up the good work!
