For my money, the older pop-apart backpack Yoda has the best scale, proportion, sculpt, and expression. His face looks like an old weary Muppet.
Any Vintage re-do should have that head.
Actually, for his tiny size, soft goods and the ball-jointed elbows are a detraction too. I think the VOTC version is about 3 steps backward from the backpack version.
Add a snake to "backpack" Yoda and you have the bestest Yoda ever.
