Here is a sample of some stuff lying around my figure cases in various stages of Chaos! Some are test paints such as the Soul Drinker Space Marines. You can see one had a lighting effect around his eye lense, another was a test at sculpting a shoulder pad, and one was a test of a blended highlight as opposed to the hard edge highlights everyone does on their marines. It was an attempt to frenchify my painting style some back in the day.
And some are just broken models. Such as my Blood Angel Chaplain... I think someone is trying to tell me not to paint Blood Angels! BAH! And some are one off tests to see if I wanted to commit to a whole army.
