Next, cut down on the roundness of your models. It's called Blockland for a reason. If you look at all the good models, they approximate round shapes with blockish octagonal or hexagonal structures. Try doing that for the round bodies of your playertypes, or at least the eyes.
Also a possible reason parts of your playertype disappear is if you name the nodes similar to the default blockheads nodes (torso, rshoe etc) such that when the game applies appearance settings, it screws up the model
