I haven't been on here for a while but I know some people are still looking.  I've been working on the feet and some of the dome.  The drive motors are fitted in the feet and the dome lights are fitted.  R2 has been built and stands on his own but is now stripped as I continue working fitting more parts together.  Here's a picture of him before he was stripped down again...

I'll take some pictures of the feet this week and upload them.

I have a video of the lights working.
