There's a long story to that actually...
A little bit of background about me first.
I'm Filipino, born and raised. Currently living in Metro Manila. Just from that alone you can probably tell where this is going.
I'm in love with the 'Nations as People' concepts like Polandball, SatW and Hetalia, however the lattermost I have a love-hate relationship with. I love it because it was my first intro to the concept (and really the characters are gorgeous) but I hate how Himaruya never sticks to a single idea and randomly adds small snippets here and there and breaks the continuity of it.
Anyway, being wholly Filipino, my Pinoy Pride™ was yearning for some home country representation, which is where the formermost of the previous list comes into play. I'm an approved submitter there (u/ZephyCluster) and I've drawn some comics of my country for the site under the characterization that I gathered from TVtropes and the Polandball Wiki.
Anyway, how does this relate to you...
Me and a friend (both Hetalia nerds with a love of research) are planning to create a massive crossover of Polandball and Hetalia. We've been brainstorming ideas, plotpoints and story arcs for a good few months now and once we were on the subject of Spain (specifically how would Antonio act around our OC Philippines - Male, if you were wondering) And she showed me your character studies.
Tl
R We agree wholeheartedly with your character studies and are using some pointers of them for a basis for our Hetalian sides' portrayals (Like our Alfred wanting to be a dad but can't so he becomes a cool older brother to our PH as compensation).
We haven't set anything in stone yet (Mostly notes shared between ourselves and some comic ideas for R/Polandball) and we plan to launch the site/fanfic/fanverse proper in April (when my friend, the artist, is out of college).
We'll be placing links to your account and your studies as references, if that's okay with you.
