I know what you mean 4/5 very powerful but try putting a little more transition and i posted a collab in which would be really nice if you read

A fine work as this has the potential to be augmented in structure and flow, I believe. Though it didn't particularly flow well, I'd still give you my props for the effort you've exerted upon writing this.

"Way nice it is so hard to be explained"

^I liked that line. It never conjured a mental image in my mind, whereas it did serve as a provocative thought. You don't have to explain it; it's (Love) unexplainable... :)

But I think it should be "What's Hidden Within/Inside My Heart" rather than behind... it makes more sense to me... at least.
