Hard rejected track! I need help!

Hi fellows, give me advice what’s wrong in this track?https://soundcloud.com/musicforyourmovie/ambient-piano-story

I can´t talk about mixing, Im in the street with the smartphone.
Maybe could be accepted with just 1:30 minutes.
Too monotonous for me.

Thank You!

It seems to me that there is some confusion in the track. The name says “ambient”, but from the first seconds a hi-hat appears, which makes it clear that the track will clearly have a rhythm. Piano plays a pleasant melody, but does not create an ambient atmosphere. Acoustic guitar from 0:35 sounds not realistic and intrusive, it’s too “close”. I like the sound of drums from 1:10, but these drums completely destroy the concept of “ambient piano”. The synth with 2:21 is not relevant in this case. I agree with Manriquedelara, the track could be 2 times shorter.Perhaps then it would not seem monotonous.

Thank You!
