Gene Stealers On the Painting Table

I love the new gene stealer holding the decapitated head of some adeptus mechanicus. It is one of the most fun miniatures I have painted in a long time. I like it so much I have been comparing it to the old gene stealers and wondering what happened to all of the little boney knobs and things that were part of the old model. I may consider some green stuff boney additions to my new stealers, as a way to add the little bit of detail that missed the model. It makes me think about the original models. The original models are very old now, but they have a timeless look that keeps them from being relegated to the back shelf. Compare that model, decades old to the space marine in the new set. I am not sure the marine is as timeless.
