My Little Pony address book mac icon

I've been making icons now. ^_^ This is Twilight Sparkle holding the Mac's Address book. I take requests!

This took about three hours to get correct. Really fun! Any suggestions/ critiques are welcomed!

This has an .icns file (mac) and a .ico file (windows).

IEEEEEEE EDIT:
Thank you so much to for pointing out my fatal flaw of this icon! I forgot her cutie mark!!! EEK! If you downloaded this please REdownload it with the cutie mark in tact!

I'm so sorry I forgot, I've been looking into getting a new apartment so my mind has been ALL over the place and I just wasn't thinking 'cutie mark'. Sorry!
