You need to watch your pedalling, there are times in the A section where the harmonies change yet sometimes you will keep the pedal down over several different chord changes which meld the sound in a rather awful way... A particular section where this is prevalent is 0:40 - 0:59. When the harmony changes, it's always best to change the pedal otherwise it sounds wishy-washy (you can tell I deal mostly with primary school kids), but the effect is there if there isn't clear pedal.
