There's a lot of issues with timing. There are moments where various parts don't line up, and this seems to be a reoccurring thing when it comes to the transitions. On top of that, there's not much in this song to tie everything close enough together to create a sense of flow and/or progression. These two factors make the song sound choppy and sporadic, and it makes the different sections of the song sound as if they don't belong together. That's my 2 cents, I hope this helps!
sory if the english is bad im not use to but i mean its touch me in the heart
wow man this song is so good i almost cry
