"Most of my songs are lower volume to make sure there's no clipping"
That's why you need to learn how to use a compressor to max out the sound without blowing that sound into shit. Compressors not only compress sounds but they can also amplify. Try experimenting with panning as well. Panning a sound in a specific direction gives off the illusion that it's louder than it really is and as such lets you turn the levels down on things without sacrificing the presence of a sound. It helps create room in the mix for more sounds.
This trick is a little more advanced and I know some artists that have gotten by without this but side chaining is another neat mixing trick. Side chaining lets you control the levels of one instrument with the levels of another which means you can set up things like lowering the volume of the bass guitar every time the bass drum hits. It's a very subtle trick but the results can be huge. I usually side chain the pads, strings, and bass with my drum signals.
There was something else I wanted to tell you but I forgot. All in all this is a cool track! Kepp on keeping on. Learn those tricks. Become the champion.
