Ask HN: Review my startup (vivapixel.com) part 2

Hey folks, after reading this http://news.ycombinator.com/item?id=890382 I thought that I would ask you to review my site again. Last time i asked was quite a while ago and since then there have been several improvements and enhancements to the site.

Key changes:

-Better UI design/color/layout

-Added photo bookmarking

-Many other changes (low level stuff to make the site faster and safer)

I look forward to your feedback. thanks
