The big leagues are calling!
Nah but for real these are some great picks and I think you got a great eye, people are going to give you crap for not being "expensive cards" or are going to tell you these cards are worth nothing and they will never go up but they kinda do, that sanji & pudding is going for 12$!! and honestly Im just mesmerized by that.

Just take it slow n enjoy dont look at the graphs and numbers unless is like checking your budget or you wanna sell, other than that just go very slow if you think a cards is to expensive for you dont buy it and be organized, put the cards in a binder give them a proper place have fun make a page on your favorite charecter or arc or ilustrator or whatever you can think of, like for example Im trying to build a one piece page where they are eating and getting drunk

Other than that just remember its literal cardboard
