Aight, sounds cool. As mentioned in my journals (it's been a few months), I'm actually going to go back and redo all of my Tasen models. Don't worry, nothing much is going to change. They're mostly going to be smoother. The only three changes I can think of are geometry changes in the feet, torso, and head, but the general shape for all of them will remain the same. I've learned a few new modeling techniques since I made those, and I realized those parts were terribly sloppy. It'll be the kind of change that makes you say, "wow, that looks a lot smoother. It's like everything's more smooth. Especially the torso, I can tell he made it more... smooth."
unless you know about 3D modeling, that's almost all you'll be able to put your finger on, just because the changes will be so small ^_^
But we're talking after the Komato, here, so... it'll be a while.
