It looks good, couple of things I would note:
1) I didn't notice your navigation right away. It could stand out a little more by maybe using a different bg shade.
2) At the top where it says login, if you actually include a username and password box (and submit/go button) the site will look like it has more authority and will be trusted easier.
3) Smaller text, when in paragraphs, although harder to read for some, can also appear to give higher authority. And to make smaller text more legible, increase the line-height.
Hope those can help with your conversions, good luck!
