I think you explained your own critique here, they aren't really making a Pirate line, they are making a fantasy line set in a pirate motif. Like Marvel Thor not looking like Norse myths because Marvel Thor is a superhero with a Norse motif.
Okay, but the thing is... Marvel Thor does not have a Norse motif at all. He's entirely conceptually 'what if Thor was real but lived in our universe and was an alien?' VERY little of his related iconography in the comics (and virtually none in the movies also) is even remotely similar to anything Norse.
I would say Thor is far more similar to Valaverse doing 'Blackbeard.' If that makes sense.
Clearly what this line is -trying- to do is 'Pirates, but with fantasy.' Like a more fantastical Pirates of the Caribbean (which also had skeleton and squid pirates). And the clothing items, if poorly done in my opinion, are a clear indication these are pirate characters. Then you get to their weapons and it's just such stereotypical fantasy trash, PLUS, the like.. two 'real' weapons that also look pretty shit.
The best comparison I can think up is imagine you want to do fantasy meets the modern world. So you design an airplane based on a Boeing 747, but you cover the thing in dragon motifs, with an open mouth carved into the nose and the tail literally designed to look kind of like a dragon tail. But then you absolutely fucking whiff it at the end by turning the wings into giant extension ladders.
It goes from 'okay.. cool cool.. I see what you're doing here and I dig this idea' to 'what the fuck is that and why did you do it?'
But again, I also recognize this is something that bothers me more than it bothers others, considering how close to funding they are already. And I'm also not trying to convince anyone else not to like them. Just explaining one of the reasons -I- don't like them.
