A nice addition to to the theme. As always a beautiful render and continuation of the concept.

The materials look great, really get a sense of the mechanics and steel. Because it's so detailed and though through i've provided a few inquiries.

Some food for thought: It appears as there's a small pulley system to spring open the 'prongs' of the arrow head. These appear to be tied to that central cord and gold 'spring', so perhaps compressing that would further the aesthetic of this thing spreading out into it's victim?

Can you throw a close up of the end of the arrow into this same shot? When looking at that end it appears as though it stems from a central rod, perhaps this pushing forward on impact actuates the 'prongs' on the tip?

Just continuing on my brainstorm here....it would be really interesting to see how these are incorporated into a quiver. Everything is very mechanical so it would be interesting if the quiver held these arrows in their 'compressed' state if you will.

It would also be very interesting to see these arrows strung onto the bow and how the bow moves. If i'm critiquing the armor as a set and not this individual image.

Anyways keep up the amazing work and beautiful project!!!
