Is this directory Structure good enough for Selenium Test + C#

I am writing Selenium tests using Visual Studio C# Express edition 2010. I was trying to find if some one is already posted directory structure for Selenium tests. Not having found one I created my own. I Curious to know how I could improve on it.

I've used http://code.google.com/p/design-of-selenium-tests-for-asp-net/ as the basis for my c# selenium tests. Although it's a little framework on top of selenium 1 you can easily switch it to selenium 2.

I work in Eclipse-Java environment, I have a "lib" folder inside my workspace, where I store all the external jar files(API's like jxl, selenium client etc.). I think you can add this folder in your Project to include selenium's C# driver and reference it from this location in your build path.
