Variations on Sakura (feedback appreciated)

I composed some variations on the japanese song sakura
Please listen and see if you like it. The first section is the original song, the next is the first variation and last is the second variation, comments appreciated!
This is the first thing i've done so it's not very complicated...

Not a bad piece...

I quite liked the rhythm you used in the first variation (the one starting with a demisemiquaver). I don't think it is practical to have the second violin playing the quaver-quaver-minim rhythm at the same time though, in terms of actually playing the piece.

In the second variation, I think you should use less octave-doubling, partly because the piece would benefit from some harmonisation, and partly because when you do harmonise I felt it "stuck out" a bit. You also need to have this in mind and look at the ending of the piece, as it feels somewhat "sudden" and the piece doesn't sound like it has ended.

thanks for the advice, is sticking out good or bad?
