Really nice track, it's quite different than the rest of the submissions for this jam. I think it has a good balance between repetitiveness and variation and the composition is great, especially for a first song, but I think you should get some better sounds, there are many good free VSTs and sound libraries. For real instruments there are things like Labs and SINE Player with Layers and some other free libraries for it, Ample Guitar is quite good for a free plugin, oh and also Ample Bass. For sound design and all the electronic music stuff there's Vital, which is basically "free Serum". If you want to make similar EDM-like music you should probably learn about techniques like compression and sidechaining and other effects you can apply to your instruments. I know that for compression OTT is widely used in the EDM world (at least when it comes to free stuff), for other effects you probably can just use stock FL Studio plugins and you'll be fine
