I like the cute synth arpeggios at the beginning, but the synth itself is pretty cheesy, and sounds a bit harsh in the upper register. The kick at :23 has a lot of reverb, and seems panned way too far to the right. Generally, core rhythmic components of your piece (drums, bass, rhythmic harmonies, etc.) should be front-and-center in the mix. The harmonic progression here is a little generic at first, and then after the sudden transition at :38 seems rather atonal. The texture at 1:03 is a little too busy, and there are a lot of rough transitions here. There are some good harmonic ideas, but the arrangement is so choppy that you’re not really using those good ideas for meaningful compositional purposes. I think you should work on transitions a lot more. Adding some drums might help - crashes, sweeps, and risers are very common ways of smoothing over otherwise rough transitions in electronic music. The mixing also needs work, starting with being a little more conservative with the panning. Still, the cute riffs, melodic flair, and rhythmic components of the piece are enjoyable. Keep at it, Calculati! :)
