Welcome to Steemit. It's good to read someone with many interests. For everything you mention you will find a community but you can also post in your blog.

Perhaps you like to join @hive-166850 or the freewriters?
Theres also the project SEA who helps newcomers grow by writing and commenting which is a good way to upvote yourself.

If you use a translator it's no problem just say so.

I wish you fun on Steemit.
