Oh surprising bass for the first track, it create tension! maybe you need more reverb for your arrpegios. Fit really well the space mood. The little synth in the back are great.
Ahah great bass motiv for 2nd track ! Nice loop. I loved the little guitare in the back. I think the mix wasnt great between the drums and the bass.
Loved the sound design of the last track ! The bass tone isnt fitting really well with the other elements who are really good.
Aaaaa love your ideas for the 4th. Great sound design. I can feel the weird robots coming to me x)
The last one do his job for happiness feeling :) It was a bit surprising after listening to the other tracks.
Overall great sound design and motives.
