When creating stylized proportions, it’s all up to you, really.
But, Rarity seems a lot wider and built sturdier than Pokey. Not sure if Pokey is just a thin boy or Rarity been hitting the gym lately.
As for hands…I don’t see anything wrong with it.
I may want to make Pokey’s left foot slightly bigger because it’s closer to us, and also maybe angle his left foot towards us a little. Like, maybe have him stand with his toes in an open V instead of parallel. You know, have his feet be like 45 to 60 degrees apart? But that’s just my personal preference.
