The one on the left is going to my Preator, whilst the other two are destined for my Tactical and Veteran squads. I've got another half dozen which I haven't started on yet, mostly due tonot having enough pins to mount them on.
Not a bad start, even if I say so myself. I love it when I reach the stage of new projects where I have all the materials and things start to come together like this.
Hopefully it won't be too long before I actually have some completed Thousand Sons to show you.
