The spacey arpeggios that outline the E diminished chord sets up a creepy vibe that is complemented by the driving drum and double bass. I am a big fan of the fanfare feeling of the brass melody. The echoey piano contrasts the sound well and adds depth to your piece within the time frame. The choir that comes in at the end on a major chord is what really gives me Star Wars/outerspace vibes. I think ending with the French horn rip is unique and and interesting way to end it. Overall, great job creating a memorable and unique theme. Your theme is short and simple and you were even able to repeat it once which drives the memorable part home. I think these are some essential components of leitmotif that you did a really good job with. Thank you for sharing!
