Beyond Face how about Hands

I become fascinated watching Kpop dance videos especially the hand movements. I see people doing lots of work on facial expressions but have not seen a lot on hands. I feel there needs to be work in this area. here is a link to momoland kpop video that has lots of hand movemeints. I wish it was easy to do something like this in unrealengine. #JusticeForMOMOLAND #MerriesStandWithDAISY Momoland - Boom Boom [Dance MIX] - YouTube
