Rather nice. :)
I like the song in general, but in the length, it get's pretty repetitive in my ears. That's properly the biggest downside on this song. There needs to be more change, and if the 8th notes you mentioned would help that in any way, then I think you should have it enter the song for that reason. But I must say, you still did well. :)
4/5 - 8/10 Keep it up!
