What I'll need from you:

Your song recorded as a demo

3 songs as a reference of what you are looking to archive with your song (The reference has to be the same genre you are looking for, I will be analyzing the instruments and technics used in these songs)

Communication, if you like or don't like something is better to know it as soon as possible to reach the result you are looking for, so don't be shy I'd love to know everything.
