Idle 1 animation has some issues. Some weapons like the Guitar and arguably Golden Axe and Jade hammer are too short. They don't seem to reach the ground, and Matt looks like he is holding them in mid-air, not leaning on them. Maybe increase their length a bit.
Also normally Matt is holding weapon at his right side, but in Idle 1 weapons instantly move to his left side. During Idle 1 some weapons with long handles like the Double-bladed polearm or the Drill look unnaturally with caped armor. It looks like the handle moves right through the cape. Maybe the weapon should stay on the right side while Idle 1? Don't know how it will look with weapon in front of Matt though. Or maybe leave the instant side switching and move the weapon even further behind the cape while Idle 1.
