the sound is much better than the previous version! I love this piece, well done! The rhythmic combination between piano and melodica works well too now!
If I may, each effect plugin should have a “dry” and a “wet” fader: when using a reverb effect, the less is the dry signal, the more the sound steps away from the front. If possibile, I would put more dry signal to the melodica because now it sounds a little bit unfocused. Also, maybe you could raise the piano a little bit too.
