Hello @dullipee.

I would like to give you advises so you can continue improving your content.

• The content is kind of short. Maybe for the next article you could write something a little bit longer, with different sections, an introduction and conclusion? That would be very helpful.
• The image sources aren't completely right. None of the images are CCO licensed according to the wikipedia you included. They are all CC BY-SA 3.0. To confirm this, please visit this link where the license of the first image is mentioned.
  Please visit these guidelines
• There are no references at the end of the text. It is highly recommended to always add references related to your writing.

Cheers!
