Great job buddy! You are very talented. I'd like to incorporate your icons in a premium theme I'm currently developing. I know that under the license it's allowed, however I always like to get the authors permission considering how much effort you put into these!
You can see your icons on the demo page of my theme (which is currently in development on the link www.thinkupthemes.com/shortcodes/icons/. I've given you attribution by placing a link on the first paragraph on the page and thanking you.
Please let me know if your happy for me to user your icons, and also if your happy with the attribution or if you'd like this to be done differently.
Thanks again friend!
