Hm, from what I can hear, your composition shows some promise. The structure is pretty good, especially for your first track. What is lacking, and I think it's something that comes in time, is the sound design. I've never used beatwave before, nor do I know what it's capable of, but basically the synths you're using now sound a bit lackluster, and the mixing is pretty much non-existent.
Don't worry, these are things that nobody knows about when they first start. What I would suggest is to look up videos on how to mix a song and learn how to make your songs sound more 'full'. A few basic techniques are things like layering synths or adding delay/reverb (I can already hear some delay/reverb in here, so that's a good start).
Anyway, at this point it's a bit hard to give many more tips than that. The best way to improve is to keep making music and experiment with everything. This is a good start, I'll be watching to see how you'll develop :)
