Hmm, I do not really know about the torso, because a skeletal dragon needs ribs. Of course, people will attack me with facts like salamanders not belonging to the dragon group, because they are actually amphibians and not lizards, like dragons, drakes and wyverns. Well, if you look at it that way, you forge a simple fact that amphibians too have ribs. Dragons, drakes, wyverns and even salamanders all have ribs. Remake?
That is a sweet design! Cleaver parts usage and excellent design make this really come together. The only thing that I would change is the head, it doesn't really look like a skull, but all in all it is pretty cool.
