Every thing looks good here. But did any body saw that if we play F and G it really doesnt suit well in the song. Although the song is in the C scale and any sequence of the C scale chords would fit well. Moreover we cannot expect such easy and simple compositions from Vishal(Pentagram) . I've tried using CAdd9 in the song which fits good.
Try this and let me know.
