I like the groovy synth riff at the beginning and the sense of build into :12. The oscillating low-mid synth at :13 and robotic-sounding synth at :25 are also nice. The drums sound a tad flat, and could use some more compression. In fact, the mix as a whole is pretty quiet and bottom-heavy. I wanted to hear some more upper-mid-range frequencies early in this piece, especially melodic content. The mellow breakdown at 1:04 was good for some variety, but also felt a tad undecorated. Filling out the atmosphere here with some reverb, delay, and/or other mixing effects could help add some pizzazz.
Nonetheless, I like the renewed sense of energy at 1:45, and the key change at 2:21 also helps keep things interesting later in the piece. You might also consider shaking up the instrumental hierarchy (i.e., which of the instruments is the lead vs. mid-range harmony, etc.). Still, the dreamy arpeggios were a good way of wrapping up the piece later on, and I also enjoyed the rhythmic syncopations during the final refrain at 2:21.
Overall, the composition here is decent, but could use some bolder methods of creating variety and more well-balanced frequencies. The sound design blends well together and fits the mood of the piece well, but is also a bit cheesy and generic at times. The mixing is a bit quiet, and could have been sharper in places, but otherwise is pretty clean and clear. I admire your sense of harmony and progression above all else - the piece is well-structured and, with a little more reverb, would also have a really full and rich texture. Keep at it, TimeTravelleR54! ^_^
