well, I really like the idea, but here are some things I think you could do to improve the realism (which will greatly improve the feel).
put a wooden frame around the cork board.
give the paper some texture (a search of google can find you some good paper textures you can use). here's a tutorial on making post it notes, maybe it will help
Design a pad of Post-it Notes | Nifty Tutorials
the paper notes you have with the curl in the corner have the cork board not fit the background cork board. it's not too noticible if you don't look to close, but I'd say it'd look better it you just left out the page curl.
also, maybe the things that aren't post it notes should have thumb tacks to add to the realism.
Good luck with your site, you're really off to a good start, though I also think you should remove the splash page. I think what you need to do is set your blog address to
http://igirlnano.com/ in your wordpress settings and then move the file
i-Girl Nano to
http://igirlnano.com/index.php
If you've got any other questions, post back here or PM me and I'll be happy to help
