you should be able to triple max th 16 as a th 15 with QC RR. that's what I have been doing. I feel like your funnel isn't done well enough in attack 1. your val & RR split up. usually it can be a fail for me cos th 15 going up against th 16 can't have this kind of error. you could use flame flinger at 6 o'clock instead of siege barrack. FF is a way better siege machine. I only use siege barrack when the opponent base doesn't give value to FF. 3 OG spell is too much. it shows in your attack #1 too. your queen almost died due to the lack of rage spell.
