It's definitely a nice piece/song (whichever you're calling it). However, I encourage you to try some new things. You having played piano for only 7 months now (likely self taught), it's somewhat hard to do that, but the continuing arpeggios, while nice, are super common now and start to get stale. Maybe try doing arpeggios, but adding in thirds or sixths in every other few notes. That'd give it some nice flare to it. Also, triplets are a beautiful thing when composing.
