Welcome to the world of making music or whatever that was called! If I were to guess which DAW you used, I'd say you used LMMS. I recognize that tripleoscillator from anywhere.

Great start! The main problem you should focus on is controlling the volume better. Pro tip: change either your master volume or the FX slider volume to 50~70%.

Really, other than that what you have is a decent melody that can probably get spiced up with the right instruments preset and samples. Might I interest you in some of the presets I made?
