[Milly 0]

Someone had a listen to 2 of my songs and despite the range and voice types of the 2 artists where very different, I was told they do not suit my voice, I know that the pitch/ notes are all correct and I pulled all the notes with out strain and the chosen vocal mode and sound color matches the original song, but I am unsure of what he meant by they do not suit my voice as he did not go into further detail.
