I don't think you should beat yourself up about your music sucking. Everyone obviously starts out inexperienced and you can't become good without first being at the noob stage, so just embrace the learning process. You'll get way better before you know it.

The reason there's clashing is that the instruments are playing in different keys. Technically that makes it a polytonal song. Some songs are written like this on purpose to evoke certain emotions (i.e. Charles Ives - The Unanswered Question), but I think the best thing to do when you're a beginner is to just stick to one key for a whole song. Music theory can be daunting but it's worth looking into at least a bit if you start running into issues like this. I recommend learning about writing in a key, but just know that it's not a rule you have to stick to always. The "rules" in music are more like guidelines anyway, and they can be broken when you are more knowledgeable and comfortable with the craft.

this is pretty good for making music for the first time. And, to be honest this critique might sound pretty stupid, since I'm just starting to make music too, but it seems like the main melody and the counter melody clash a whole lot. It makes listening to it a bit hard on the ears, and gives off the vibe that the song should belong in a horror game. Which if you're going for that vibe then ignore what I said. Anyways, this is still a pretty decent piece of music and bonus points for trying a DAW out I still rawdog my shit with my keyboard.
