Personally I wouldn't release a postbit like that for free, although it's pretty much the same as the usual "layout" of postbits, it's still quite attractive once touched up in places...

good work.
One thing to remember, when re-designing a template is to completely delete the contents of the template, and re-design and code from the start, and make it unique, ie. move things around and don't keep the standard layout

just a thought...
nonetheless good work, and releasing it for free to the public is very decent of you, you must have a lot of free time
