Welcome! Love the stickers on your binder. Looks a lot better than mine, since I just put every Pikachu sticker I get for free with orders randomly where there is still space, haha. 
You may have already seen it, but if not, I wrote this article about all Base Pikachu Artwork variations in case you’re interested. Good luck with your collection goals, and enjoy your stay here! 
Greetz,
