Well, I've seen what can be done with the other figures as far as resculpting and repainting (i.e. Aragorn and Legolas), so I'm pretty sure that in the right hands these can be made to look even more like Elijah Wood and Sean Astin. This is just my unqualified opinion of course. I have yet to see the Sam and Frodo 1/6 in person, so it could be the lighting conditions under which these photos were taken. The Aragorn sculpt looks much better in person under natural light than any internet photo I've seen of him. But then again, from web images, the Gandalf and Boromir 1/6 look near perfect.
Please take my opinions with a grain of salt. My personal thoughts aren't worth the crap paper I use to wipe myself with.
