Because I have a friend who is half Iranian, I have seen a lot of carnelian seals from Iran. They have a string with about 50 of them on it from their family.
What stands out for me is the lack of starter rounds in any of the areas. The seal makers would grind round areas first to remove a lot of material, then they would connect them by abrading with straight tools to make the arms and legs, and details of the body. This seems a bit unusual to me.
It is off-center a little too. This is usually caused by being unused to working with grinding tools on the rock. People do this on the first 4 to 5 seals they make, then figure it out and don't do it anymore.
Some of the seals my friend had were off center too, but not by much, and it could have just been from wear, or from the original stone being turned down by grinding so it would fit in the bezel of the ring.
I think there were one or two they had which used a straight tool method like this, but it was much more rare, like 2 examples out of 50.
