Hi Marek! Great work on the songs. I feel the creativity in the pieces.
In "Startup", you should try and dynamically move the flow of the music. What I mean by this is to create automation curves that adjust things such as volume, filters, panning to create a living and breathing mix. Automating volume is especially important, as it really is what separates the professionals from the amateurs.
A number of your tunes are aligned too much on the low-end I feel. I know you might not want too much high-end frequencies in your songs, but maybe a slight boost in some instruments can help fill out the sound spectrum. "In the Name of Science" is good example of a song that needs some high-end.
Lastly, I recommend tuning the velocity of your instruments to replicate a human performance. You do record yourself playing, which is always great, but there are some instruments that are a bit too stale (percussion in "Encounter" for example).
Other than those points, I enjoyed the sit-back-and-relax nature of your tunes. Loved taking the time to listen to your creative works!
