Nice work! I like it, just a little bit feedback :
- I think it'll look better if you place the graphical options above the text links.
- Give your Adsense a slightly different color (more attention to your Adsense links)
This is what I mean :
- Also, a mouseover for your links would be better. Something like dark blue would fit the site perfectly
- Below the description of the 5 free services, add a (text)link with [more] or something similar which will link to the dedicated service page. So users can go to that service by either clicking the image or the more text link.
- I would also suggest to use a slightly darker font for the text (just a little bit). It will probably will read a bit easier on a white background.
Good luck
