Kriana is a lovely and unusual name. What makes you want to change your name?
Krystal is a pretty name too but I think it's a bit trendy. So if you're looking for something different I would go with Kriana.
Although I do quite like Niamh's suggestion of combining the two.
As for my dream name...well that's a toughie. I really don't know what I would choose. I used to really like the name Fiona, but in light of Shrek, I don't think I would ever go for that name now :P I also like my middle name, Erina, but it's often mispronounced.
