Knowing me i'd probably fall off the cliff...
Ok, you've got something good going on here. I like the beggining, peaceful and what not, and i like how the synth at 00:23 comes in, but i was really expecting that to be accompinied by a beat at somepoint, and it was a bit disapointing.
I love the Guitar tawords the end, that really gave this song the "walking away" feeling you mentioned. Plus it kinda gets you pumped in a way. I think that sounds tight as it is, but maybe some rock drums wouldn't hurt.
Now, I find the the ending just a tad to sudden, I'm thinkin that if you held out that last chord over the cymbal crashes, that would've sounded better.
Overall this is pretty simple in its entirety, but it has a good sound to it, and dont get me wrong, that guitar ending was great, enough so to maybe make it a little longer, should you have the chance, so keep'em comin :}
