I prefer Qiara.

I have always thought that Qu makes a kw sound and Qi makes a ki sound. I agree that you will get a lot of 'so how do you spell it', but I have a traditional and traditionally spelled name and I get many (MANY!) variations! Either way you are going to get someone spelling or pronouncing it wrong. (I once had someone spell Jones as Joans, how hard a name is that to get wrong???!!!) If you like it go for it, not everyone has to like what you do!!

IMO it's complicated, confusing and looks a tad too made-up - although I'm really not a fan of "kriatyve" spelling. I much prefer traditional spellings - it's adds class to the name. We have a bit of a joke going in my family that you could technically spell ZAC as XAQ Sometimes it's just bit silly! But I think Qiara is fine!
