Hi @thethinkingdr. Brilliant piece of article. However, I would like to make a few suggestions to make it better:

• You need to attribute your image properly. There are three things you need to have in the image's source which are the link to the source, the author/owner and the license version. Refer here if you want to know more regarding image attribution.
• The 6th image which you are using might have some issue with the copyright law. Please refer here if you're not familiar with what I was talking about.

Please note that I'm not in any way, try to disapprove your work. You've done an excellent job here, but you can make it better. If you have any problem regarding STEM-related articles, you can join steemSTEM Discord Channel and we will be glad to assist you.
