You have not been rejected, we just did not discuss whether to put these up or not. Actually I thought you wrote it was not meant for the site but I now see that only referred (rightly so) to the German song. If you'd like these up the site, no problems with that ! Though I still believe that with some more effort you can still do a lot better, and you'll be more proud of it.
I feel more comfortable play the harder pieces, above, by myself and for myself.
I think that is quite common. But as Schumann already said, it is better (and far more difficult) to play a simple piece really well, than to play a difficult piece raggedly. The trick is to learn to hear what you actually produce, rather than what you'd like to hear. Listening to yourself critically is essential practice (something Hamelin said, I think).
