It seems like half of people are in love with the Fennec Shand animation model, the other half hate it. I’m okay with it - it differs only slightly from what Fennec looks like in live action - but I think we need to see it in motion, and in the final product.
Tarkin’s model is similarly very sharp-edged, more so than either his Clone Wars or Rebels designs, and in the trailer I thought it looked fine.
