Hey @Alant! I like this a lot. It does sound like it could be the soundtrack to a chill video game. I actually think a mixture of instruments would be favorable! I preferred the deepness of the bass in the first version, that was really nice, though i like a lot of the new stuff in the second version too. You could combine them.
As for ideas for what could come next, if it were me, i might do a pause followed by a big tutti g chord, and then continue in G major. And maybe do some inversion and retrograde with the motifs you have?
