(this is all based on my opion, so nothing personal)i love the piece but for such a grim story,At parts it almost sounds to happy, or bright, the G major key is usually bright sounding, (to me anyway)
and really, i think the 2nd movement is more like an intermission
Finally the transition were pretty good for such a young age, just a couple of minor problems, mainly range problems, but still, gorgeous piece,
