If you need some good icons and don't mind ones from commercial games, you should look at EDITED in the Rune Factory (DS) section. There are more than 600 RMXP-sized icons from this game on the site and they are all very good.
If you use them, don't forget to give credits to both the game and Fogu!
Use the official Resource Link thread (http://rmrk.net/index.php/topic,131.0.html). We can't flood the forum with a bunch of threads that only link to a site.
