I really like the whispery arpeggio and the brass melody makes for a nice villainous atmosphere! The abrupt ending is also very nice. One of my favourite sumbissions :)

You did a great job of sounding both confidently familiar and very different. My favorite parts were the contrast between the whispery rhythmic beginning and the sudden brass/drum entrance. Also loved the piano ornamentation around 0:20-22 (I might have even made it slightly louder).

I feel like this one really embodied a "larger than life" level villian by using the heavy brass and that arpeggio. I can also really imagine this motif being a recurring segment of a game/show that I would absolutely remember, well done!

God that icey arpeggio was wonderful, you really excelled at representing a character in such a short ammount of time! 

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!

This sounds so much like a Star Wars' Death Star approaching -kind of thing XD It fits the avatar alright. I particularly like the starry scale.

That melodic line is nice and dark!
