The only thing that's sticking out to me is the grey cheek vent. On the actual helmet the indentation it sits in is slightly larger than the piece itself. On yours it sits flush.
Also on the bicep, I think the cutout on the inside arm should maybe be more of a sharp z shape. Yours is more of smooth transition between the higher and lower section.
That being said, they look fantastic andI'm very much looking forward to this releasing. Ill be buying these files day 1.
