#20 is definitely going in the right direction, very clean logo. It would be possible to try out a different font for the name "Claudia"? Maybe just a little more curve, less block style text, just to see how it looks.
And I would like to see a version with .com added. Maybe the same font used for Claudia, but smaller.
Other than that, I'd just like to see some depth added, web2.0 style or other stylizing.
#37 I really like how you used the hallow heart for making the the 'O'. Can you make the heart dotting the "i" about 20% smaller? Also, if you have any variations on the X, I'd be interested in seeing that too. With the rest of the logo being updated, it doesn't feel like a perfect fit anymore. If I think of anything design ideas, I'll be sure to post.
