The details are not very sharp, it actually looks like it's been recast from another helmet, be great if we could see the molds used to make these.
"Recasting is a process whereby someone takes a prop that has already been made and makes a copy of it. Props are sometimes 100% fan created, sometimes are found items (e.g. a henglster counter that they bought), or from a private collector prop such as a screen used helmet that someone bought at auction.
The whole argument against recasting is to protect prop makers that we depend on for our hobby, pure and simple. Let's take the case of a fan made item such as TM's armor. He put an awful lot of labor in to making this and by selling copies does the rest of us a favor, as creating your own fan sculpted armor is out of reach for most folks. By recasting his work it is a dis-incentive for him and others who do fan made props to offer anything up for sale. No fan made props heavily curtails our ability to enjoy our hobby. So member of this community go out of their way to protect this person's art work as we'd like to be recipients of his labors."
We have a whole section just on "recasting" https://www.whitearmor.net/forum/forum/225-recasting-discussion/
If it's not "recast" then I would suggest the maker adjust his/her molds to make the details crisper.
There are other helmets available out there with crisper details and I would suggest purchasing from there, here's our "vetted sellers" thread
