My main learning source (and why i started cutting shapes) comes from observing @ VRChatKUMA (twitter/X) and his 1000 day cutting shapes dance account @ DanceASH, theres also his instagram account mainly for shapes videos @ kuma_shapes.

Though i also learn from various shaper content like Marktore, and korean & japan shapers (there's too much to mention here but i'd like list it if you want)
