Vibes are great on all of these and fit the sci-fi theme nicely, the rhythm and chordal movement on the Boss track gave me some big Pokemon battle feels 😄
On the production side I felt that the "non orchestral" sounds could've used some fiddling around reverb and EQ to blend them better with the acoustic sounds, since the orchestral samples are a lot more wet/less upfront sounding while the synths etc. were a lot more dry/closer to the listener making them both feel they are in separate spaces to me when playing together.
Good work!
