The arrangement is good, even though i don't like some parts but maybe is something personal. First of all, the kick sound from the drum is no where to be found, in some places you can hear it, but in others is obliterated by the other instruments. Also, when the song starts there's like a strings volumen going up, but they are going way too high. The piano sounds stranges in some sections of the loop. You should EQ better the keyboards instrument (string, piano,etc.). Of course this is my personal review, hope it helps.
Good luck
