I am by no means a musician, even remotely, but I'll deposit my opinion here as well as I can. They all are nice, and fit fine, but I'll keep it constructive and let the rest praise your music .

In order of goodness:

- Besides you
Nice tune, a bit empty though, short non-echo-ing sounds tend to sound so midi-like. I like the flute-like sound at the start but too bad the last tone is pitched up instead of down. Then comes the xylophone-like tune, but you could have added a 'couplet' in there, and the ending part of four couplettes takes a bit long.

- Strange to stranger
Nice and slow, but the background bass is a bit disturbing/noisy, I'd even it more out. The piano is random as it doesn't come out with a clear pattern but that's okay as the tune is slow and relaxing.

- Leaf on the breeze
Good action tune, but I would soothe the guitar-ish sound more, and maybe slow the tempo down a little.

- Time
Sounds a bit random, try to get a more catchy, structured tune to it.
