Normally I shy away from icons like this myself.
There are so many around but you made them different enough that they sort of stand out from the crowd.
I really like your piggy and tut buttons here!
Software Support Icons

Users of RealWorld application may already know some of these symbols from the "Love it!" tab of the Online page.
The purpose of these icons is to help software authors to promote their applications and get in touch with users.
These icons were originally drawn few years ago in RealWorld Paint, but I have re-created and updated them right now while testing the vector layers that will be available in the future version. I will release the vector sources when that version is publicly available.
