I like the tranquil pads at the beginning with the pulsating effect. The piano at :19 has a bit of a strong attack, and the super high-pitched harmonies could use some smoothing out, maybe with a bit of wet reverb. In general, the texture is missing some lower-end frequencies. I'm really liking the rich harmonies and sound design, though. Also, the percussion deserves to be a bit more prominent in the mix at :54.
I love the muffled brass synth instrument at 1:20, and also the smooth transition into the bare-bones breakdown at 1:47. Between the brass solos and injection of energy towards the end, the piece comes together nicely. The brass did sound a tad undecorated in the mix, though. Again, some more mixing effects on the lead melody and higher-pitched harmonies might help the different instruments blend together a bit more. You seem to have a habit of going all out on the mixing effects for one instrument at a time, but not the others. Also seemed like the very end of the piece cut off suddenly.
Overall, this is a neat, smooth-flowing piece with some rich harmonies and strong instrumentation. The mix could be a bit better balanced - it's currently tilted towards the treble end a bit too much, and at times could use a more well-rounded sense of atmosphere, with all of the instruments gaining some depth in the mix with some more reverb and automations. Still, I really like the funky filtering stuff going on during the last 12 seconds, and the piece lives up to its name with a pensive vibe. Keep at it, P1con! ^_^
