Agreed. As for sanding down the brows, etc., I sort of feel like that is going a bit over the line with respect to the hard work that went into the sculpt. I like the feeling that I'm working WITH the sculpt (and by proxy, the sculptor) to create the best figure possible, instead of re-sculpting, sanding, cutting, etc.
I know a few people on this board have done wonderful things by shaving off bits of face and so on, and I respect the work they've done. Much of it is quite amazing. But I personally shant be doing it. I think you can achieve great results without the exacto.
With regards to painting Luke so he's looking more up, I have two reasons for not wanting to do this.
First, it limits his posing options. His neck articualtion is such that he'd always be looking up. He'd never be able to look down at Leia, a funerl pyre, his robotic hand, etc.
Secondly, I already did this with my Anakin, and I don't want them to look too similar.
