I am on a sideway now (although..) from collecting Star Wars and started to add the incredible Toybiz LOTR figures.
For repainting and customizing is my hobby like yours, I did this with Gimli:
I had some issues with this figure.
The right hand broke of, so had to be fixed with a screw.
The throwing action is backwards, instaed of forewards.
To get under the beard when painting, I had to break off the head. It is glued again and can move a bit like before.
How do you like it?
The display is in my diorama of Fangorn - see: Treebeard in Fangorn LOTR diorama display (WIP)
