Uplifting
Very nice tune you have here. It has that slowly uplifting feel that reminds me slightly of Vangelis' work, which I believe can only be a good thing as far as songs like this go. The name you picked also works very well with the style, and I can easily see this song used in a scene of first flight of any sort.
The sounds you used fit the powerful rythm and mood of the song perfectly - the short strings along with the piano are the main driving force behind the feeling of this song, and the drums only added to that powerful build-up.
In my view, it has the right amount of epicness and that "mighty" feel to enable it to stand as is, without any additions. As for expanding on the song, I'd suggest a soft synth string intro that would blend into the beginning of the current version to accentuate the crescendo of the song that you've accomplished so far.
Very nice piece of work, can't wait to see what the final version will look like!
