A Review of Iconfinder | Search through more than 114,000 icons by Tom Dunn

Definitely a great start, I really like the logo and the drawing looks really good. I also must say this is a great idea, I will be using this!

I would, however remove and resize a couple of elements to achieve the clean look of Google.

The text below the logo could be a little smaller. Also the search button might look better if it had a hint of your colours of blue and green.

The links at the bottom seem to be a bit crowded so I would suggest moving or removing some of them, or at least re-styling the 'hosting supported by...' (for example align to the right and with a colour of grey).

Also I think to create a more spacial feel you should space some of the things out on the page, leaving a bigger gap between lines.

Overall it looks great, just needs tweaking a little and it will look really good.
