So here is the story, vantasss is a friend of mine IRL! We each had our own potterstuck ideas, she puts hers into her intros for the cosplay photosets, I put mine into my fanfic. There are many, MANY places where we over lap, and we have given each other ideas! We have a TON of fun doing the photoshoots together, and those shoots incorporate many of our ideas!
But yes, at the end of the day, there are some differences, as they are two different mediums by two different people. For instance, in Spellstuck, the Alternian set of trolls from the original canon are 4th years, where as in the Potterstuck Project they are 3rd years. There are also some characterization differences too - for instance, in JJ’s intro, she mentioned Aranea hadn’t been around Meenah much recently because of Slytherin Quidditch practice. In Spellstuck, Meenah is actually not at Hogwarts and hasn’t been since the first week of school, for reasons that will be relevant to the plot later on! Also, in Spellstuck, Cronus is not ‘mugglekin’ (though that idea made me laugh my ass off!) There is a different explanation for his love of humans, and it started to come out in chapter four.
So yeah, tl;dr, we have a LOT in common and many of these photos incorporate Spellstuck ideas! I definitely hope to continue to collaborate with these lovely ladies because it is a blast! But you can expect to see some differences. Personally, I enjoy it, it’s great seeing different takes on things!
