Howard Stark,
Thank you for the suggestion.
You suggested to use direct lighting set up.
The slit should go on the top, bottom, and near the nose, so it'll create the eye shape.
I am not a fan of this set up since I am gonna wear my glasses, the visibility is very limited
Light spray on the eyes, that might work. My previous Mk4/6 is using very bright gold color, which is actually semi-transparent metallic paint.
It just need a silver-ish base color
Omarbou1,
When I modeled this, the pictures of the big action figure was not out yet. So yeah, I am not saying this model is 99.99% accurate.
Imagination is added too

Even the FB released picture is different than the action figure, or Starboost.
As for the handplate, I was using the children handbook pic as reference. So does everything on the back side and side view.
Seems that the action figure just use the same mold as Mk42.
I do have Mk42 files, or there are free versions that already available.
So no problem in that department. Good catch.
I am not gonna discuss any selling here, but all I can say is quality, delivery and price goes hand-in-hand.
