Yeah this is a dope collection, great how each melody you made blended into the next. Despite it being a collection of diverse melodies it's fairly cohesive and enjoyable to listen to as if it's a single track. You have a lot of great sounding ideas, all of these would make a great song.
My fav is definitely melody 7 - so light and heady, inspiring!
I think I'm gonna have to try doing something like this. A lot of my ideas usually end up as single projects that are 30s long. Most of them dead :( but sometimes revived.
