I do have another nitpick.
It took me a while but I finally figured out what's not working with the pose - by comparing the ARH piece to the Laocoon, you can see that the Laocoon has a slight twist of the torso, while Perseus is sculpted upright.
This makes a big difference in pose, because the twist indicates movement/muscular tension, while the firm torso makes it all look like Perseus is striking a pose, it's not very natural.
Also, the face looks a bit emotionless. It could benefit too from a slight tilt upwards, like the Laocoon (but not so exhaggerated).
Pics for reference and comparison:
Any chance this could be tweaked? It would only need to fix the 3D sculpt and reprint the torso. I seem to recall from the pics on Facebook that the torso has been printed as a separate piece.
