Hi @motey!
Here I am again trying to help :)
Your post is very interesting but should indeed include some links to sources. As well the pictures you use as also the statements you make.
Don't forget: everything you write on steemit will stay forever in the blockchain - even if you edit it.
There are a lot of sources for pictures you can use like Pexels, Pixabay and more (just google them).
And interested steemians like to investigate ... so give them some sources where they can read for themselves ;)
You know what you wrote in this post from some sources - just share them.
If you quote your source just let the reader know by using a ">" (without the "")which looks like this in your post:

This is a quote and not my own content.

Steem on and don't get scared about steemians who might let you know about this in a more direct way ;)
