Creating your own framework is good thing. I think every developer should make it. But it should have some concept. Why you require it when it is already developed by someone having more features. If you are serious about making framework with some concept, it should be well documented irrespective of user [may be you] and this is the point where we probably fail. I had seen, most of popular framework is well documented. Again provide the examples files, so the concept should be more clear.
You should probably use your framework in serious work otherwise there was no new development in any subject, but sure to clear your picture. Dont loose confident.
