Hi there, well.. I got fed up waiting on Lego to make one, so I decided to have a go myself, I'll be putting up the pictures shortly.
Please note! This is someone else's design & pictures and full credit should go to them, I just copied the idea.
Based on this I've used the following list of parts so you get the idea.
For body and legs, the Tusken raider.
For the head, normal smiley face.
For main helmet part, a crystal ball.
For visor parts 3 round clear 1x1's
For tube holder a L. Grey "T" junction.
Added for effect 2x(1x1) D.Grey tiles for weight's on boots.
You will also need some Bronze paint (I used sliver.) and some superglue.
Here's the pictures (Rather large though, due to the camera settings) so you have been warned.
They show some customs I've worked on as well as the latest.
Ps. He's not finished yet, but you get the idea when the gallery is released by brickshelf.
