Songs in my profile labeled "Intro"

I need an opinion on wether I should keep working on this or just throw it out. It's for a composition at school.

I would keep working on it, however, I like it when people use NON- power chords, cuz power chords are just too... easy. sounds great though. I would like to see you finish it. Check out my songs if you have the time.
ok the ideas are great, but seeing that is an intro i would stick to probably one or two riffs and extend on them, within the 23 seconds there was 3 themes,

Introductions are there to either grab the attention with sound COOL straight away or to go and have a large build up

im not saying that its bad im just saying extend on the first one cause that sounded cool for the 7 seconds that it lasted
