I enjoyed how in the intro each added instrument changed the rhythmic context of what came before. It started off feeling like a waltz with those initial triplets, but with more instruments eventually was felt in 4/4. At first I felt a little like you were holding back, waiting a repeat longer than you needed to to introduce each new element. But it did start to feel a little chaotic to me in the parts in the middle where everything was together.
My favorite part was the last two minutes, when it got minimalist again. The texture of how the synth wave and strings fit together felt really pretty and celestial and ambient.
The name is great too, the repeating midi lines do sound like this star is sending out signals.
