I have to agree with a lot of the comments I've read. First off, the pic on the bio really does have to go. I won't be as blunt as Xterria, but I will say, like Ober, that it _really_ is not becoming of her. I would also go with pic #4 (I didn't look at them all but it's a good pic).
I had the same thought about the main picture. Somehow you should try to make the background fade to transparent toward the right.
About the 6GB/mo, what is the hosting company the site is running on? I know PowWeb provides 5GB/day for about $7 and Brinkster provides 30GB/mo for about $7 also. It really depends on how popular you think the site will become. With all of us checking out the page you said it's eaten up a mere 30MB? If it did that much traffic every day it wouldn't even exceed 1GB, so I think you're alright.
