Thanks for inviting me to join your contest! ^^ Here's my entry.

I really like this because of its simplicity and its positive outlook on things. That quote is one of my favorites, and Ichigo is my favorite anime hero (making Bleach my favorite anime).

I'd probably recommend this to people because of how happy it can make you just by looking at it. Studies have shown that seeing other people smile (whether they're real or not) will drastically improve your mood.

Edit: Woo! This was a Mod's Pick! I'm so honored. ^^
