Hey bud, well done. I would say for the Gnosienne, listen to a few recordings, due to the fact it has no time sig, although clearly 4/4 , it's interpreted quite widely, so it's always a good idea to listen to a few recordings. Also it's a little slow, so the temp needs working on before xmas, but I assume your still learning them. Perhaps try to make your grace notes a little smoother and closer together perhaps.
Le Onde is difficult to say because you have a slightly simplified version to the one I have, but you seem to play it nicely enough, good tempo as well. I would perhaps try to accent to melody more on occasions though, just think about it in your head, and it will probably come through naturally.
Well done, nice pieces, and don't forget to enjoy yourself :p
