Image on the left is the offical model, most of the key points are very close when the model are placed side by side. Some of the marines proportions are just kinda off when you try and place a human form inside the suit as there's no way that human legs would fit properly through the suits hips.
One thing that throws the printed model off a bit is that the arms stick out slightly too far, I've since cut them loose from the model and cut down the cylinder so that they snug up directly with the torso which definately helps.
I may need to thicken up the hoses in the groin and lower torso. Part of the thinness in teh pic is due to it being head on, but part of it is them also being a bit too small.
As for getting the priming done I'm missing the mixer needle for my airbrush, not sure where I placed the parts when I cleaned it as it's been about 6 months since i used it. May not have have cleaned up pics for a bit
