The first track flows well and its instrumentation is nice. It has bits and pieces that are a little discordant, but since it's meant to be a little bittersweet I find it fitting. I like the way you use the piano in the second song, it feels very organic and free, I like its little flourishes.
I'm not a professional composer or musician, so I don't feel comfortable giving you any direct criticisms on what you've made. However, I can give you my personal advice, and that's that if you enjoy making music and wanna get better, you should keep going out of your comfort zone and trying new things. This can be participating in jams, trying to make songs in a new style, maybe learning a new technique or bit of music theory and trying to apply it to a song. In my opinion, all of that is what'll make you learn the most and realize what you enjoy making. That's how a lot of people find what they want their main style to be. I hope that helps!
Regardless, nice submission, I had a good time listening!
