I love the mood at the beginning, as well as the instruments and dreamy vibe. It fits your image of space explorers perfectly! :D I wish there was more substance at times, but still very catchy and nice job varying it. It's energetic and techno-y, yet also strangely atmospheric and harmonizing at times. I loved how you ended it with a creepy mood, but I personally didn't think you needed the rift at 4:43. Anyway, it's an overall excellent piece! Keep it up! ;D
