Yo! So this is your first ever song? It's a nice solid start! I like how you've got that weird "E" or "C" letter in the title too. I don't have any symbols like that on my keyboard. Well about the song, I like the beat. However, it doesn't make me think of anything having to do with the U.S.A. Also, you could improve it by adding in more variation depending on where you want to go with this.
First off, whether you want it to exclusively be a drum and base track or perhaps instead add some tunes is up to you. You could go either way with this. As it is, however it's plain. It's... rather linear, heading in a predictable direction. Don't get me wrong predictability is good to in a song, but if I could describe this piece as a line chart going left to right, this would be a piece with a plain gradual rise to the climax point that starts around 2/3's of the way to the end. Nothing too interesting or memorable happens throughout the entire song though.
Also since it sounds like you're just starting out I'll shed some advice that may help your future music on NG. It helps to know what you're making it for. It sounds like right now you're going for an entertaining, fun-to-listen-to-any-time kind of song. That's cool and ppl commonly like that stuff on here I think. But the other think that's also cool to make is music that can be used in a movie or game project, something with a theme and expresses a mood or story. I myself have trouble making that fun-to-listen-to-any-time kind of music. I post a lot of background type music that I have a lot of people messaging me asking to use in their game or video, which in my opinion is a great way to get noticed, especially since ppl start hearing it outside of the audio portal that way.
I can tell you from personal experience making music, just have fun with it and make it interesting! If you catch your own head unconsciously bobbing to it while working on it that's the first sign that you're on the right track! Hope all this is helpful toward your improvement!
