Boardgaming is not a matter of life or death...
...it's much more important than that!
I do know this one single promo tile for a game that isn't being talked about much anymore is almost a decade old, and I am aware that nobody might even care, and also, somebody else has almost definitely said this somewhere else on the internet... but I just have to say this:
Thematically, a "Samba School" on Cuba is way off!
Cuba=Salsa (or Casino, or Son, or Rumba)
Putting a "Samba School" tile in a Cuban-themed game is like putting a "Karate School" tile in a Japanese-themed game, or a "Sushi Restaurant" tile in a Chinese-themed game. It's mixing up the cultures.
Do some research before you publish your stuff!
I'm pretty sure there are Karate schools in Japan as well as Sushi Bars in China. Not sure about Samba schools in Cuba though.
