Hi Justin!
I looked over the 3D Props NL pictures as well and I think the armor looks good. Overall I am impressed with the level of detail.
I'm not sure if they are missing the shoulder bells or the elbow armor. This image seems to indicate that the narrow piece could be the elbow armor because there appears to be something above the forearm, but I'm not positive.
I also noticed the thigh has some layering that I'm not familiar with. Here's a reference shot and the area that stood out to me in the 3d print.
While there do appear to be some layering differences, I think the thigh still definitely retains the overall appearance. Perhaps @DarthValkyria can chime back in about whether the typical GML would approve this. Or maybe that would be a good question for your garrison GML?
