The Cosmic Clock: beautiful little pizzicato melody, and I love the trilling woodwinds. This track is super mystical, and utterly packed with character. I was initially going to caution against having an ever-repeating bassline with different things going on above it, but there is so much character and so many different vignettes, I couldn't possible complain. It has a really mechanical feel to it, and brilliantly orchestrated. Would work great with a live orchestra! The singing was an awesome addition.
Ticky Goes To Town: You've established a quirky, whimsical world, and this piece certainly follows in that vein. It is strikingly similar to the Second Waltz by Shostakovich, though. Definitely be careful-- it sounds like you're dancing around Shostakovich's work. 1:52 is a point where it sounds more like original work. 2:10's flute motive is lovely! Again, 2:30 seems to be a direct rip of his orchestration.
Ticky Goes To Another Dimension: this track, despite the steady drum, feels slightly disoriented because of the offset harp-- brilliant effect. There are some times where the mix feels a bit imbalanced, with certain instruments sounding closer to the ear than others. Again, the addition of vocals is really cool!
Overall, I loved this soundtrack! Your production is really good. I still have mixed feelings about the Shostakovich quote: it's a delicate thing, because I'm sure it's in public domain by now, but you showed that you can compose a fun, playful waltz without needing to copy somebody else (1:52-2:30 all sounded original to me.)
Nice work, and keep writing!
