Well, not all composers can superbly play everything they write.  Composers who write or arrange orchestral pieces can't usually play every part, because they don't actually play all those instruments.

Writing music and playing it are two different jobs.  Many players never compose any new songs themselves. 

However I certainly do agree that it would be a delight to hear iBud playing some of these pieces as well.  It is a rare and very special treat to get to hear someone play new music that they have written.  In some ways, nobody will ever really play a piece like the person who wrote it.

But I would view that as a separate treat, and if iBud is not comfortable doing so at this time, it does not detract at all from the achievement of writing some very nice and listenable pieces.  An excellent achievement in it's own right.

They are good pieces, listenable and playable, and iBud is very kind to share the written score, an audio, and even a backing track for those who might like to try playing them.

Bravo!
