Hi everyone! This is my first contribution!

Hallo I'm writing about my home town.
My town is on  a small island.
There are many beautiful animals and good nature scenery (not sure what you mean by nature, is it scenery or wildlife? 'nature does not explain what you mean) and many cultures (not sure what you mean by many culture, do you mean 'many cultures or 'a good culture?).
For example, white beach, blue sea, flightless bird we called "Yanbaru Kuina" and a dance dedicated to the dance we call "Eisaa". (a dance dedicated to the dance we call 'Eisaa' does not sound right.  It is not clear what you mean by this).

Overall, your English is quite good. Well done.
