Hey Deku - I'm really glad you threw in all the field battle themes as well in this one.
My problem is not with the left hand, but rather the right hand. In bars 6, 8 and 12, as well as all similar bars throughout the piece, you have a long note, followed by quaver triplets. This clashes with the left hand (a bit) and it feels out of place. I think rather that you should say, for bar 6, have a dotted crotchet followed by two semiquavers.
Everything else was pretty damn good. I can't help but feel that there's not a lot happening at bars 67-83 but I know it's an accurate transcription of what's happening. What about a little experimenting?
