Very cool ambiance, I like the textures, especially in Red Shfit I think its the best of the 3. Discovery is pretty unique with cool sound design but still follow Red Shift in terms of vibe. Ascent is pretty different from the two,it fits the space theme but in terms of whole album I think you tried others synths and approach to it which lost a tiny bit the follow up of the early two tracks but still a nice track its probalby just the frequency spectrum that the other twos are in mid-low range and this one is more playing in the highs, the arrangement still connects with the first track. Good job !
