While it's not your best work, it still has that "little" something. The part I especially liked, starts at 0:45.
But in all honesty, this is more of a song I'd like to listen to instead of using it in a game/movie. If you want your music to be used in games or movies try to imagine a scene in your head and the music it could fit to. Take your song, that was used in that flash movie, for example. It fit the movie pretty well. Congrats on that, by the way. :)
Also, since you won't be able to make songs longer than 1 minute, why don't you try to make loops of a minute sometimes. People might use them in their games if it's what they're looking for. Again, capture the atmosphere. Imagine a situation in your head. If your intend was to make songs people could listen to, forget the points mentioned above.
Another advice would be to collaborate with other people here on NG. Check out the forums and news posts to see if people need music, maybe participate in contests. This way you will make yourself a name here.
I'm looking forward to the day you'll finally get that long-awaited new PC. Else there's always the possibility to drug your father with sleeping pills and get to make songs every night without him knowing. Hope the advices (even though I'm more an artist than a musician) could be of any help. Keep doing what you love doing.
