I think the second recording is delightful, and shows a lot of compositional prowess. Writing a captivating slow movement is very challenging, and you pull it off. You tell a lovely story with that progression, and your melody goes on a couple (pleasantly) surprising turns. It all holds together well and creates a delicious little package. A pleasure to listen to!
The first piece is a good start, but doesn't have the same artistic quality as the second. My main recommendation would be to practice writing something more interesting for the bass. The Alberti bass can sound cliche in ten seconds if not handled with care.
I recommend listening to the first 15 or so Beethoven piano sonatas. Those are an incredible tutorial in how to try different ideas for the bass. Beethoven never lets Alberti bass go for an entire piece, but instead it is one of many tools in his tool box. The key is he uses it when it is artistically pleasing to do so, and moves on to other rhythms for the bass when the moment has passed. Since you are an aspiring pianist, playing through as much of those pieces as you can is a learning experience of enormous quality. Check out the last movement of his second piano sonata for a great example of how he uses Alberti bass selectively.
Keep it up! You've got a real talent here. I am surprised to hear you haven't studied much theory. You're very good, and as you study more theory you will only improve.
