Hello, Imba!
I also came up to that conclusion about enhancing volume on melodies, it's gonna be pretty much better.
By the way, i'm from ukraine.
I'm still thinking about how to improve my production, but unfortunately for the present moment me and some other people are not satisfied enough with the result May be it's the matter of experience and better understanding of what i'm doing . But anyway i like the sound of my music whether it's good or bad.
