I had this one coloring book that had the most basic animals and I made every one of them look real and 3D!
Wow! How many coloring books do you own? 
I have 3 bookshelves. One of them is full of romance novels, The other two are overstuffed with mostly fully colored coloring books!
That's a lot of coloring books! How many have you turned into amazing scenes with crazy backgrounds and beautiful shadowing? 
Most of the pictures on the second book shelf. The larger first one that I filled up was mainly me practicing shadowing and adding things to from watching youtube videos. I also took a few classes online that I paid for and learned as much as I could. The second book shelf I bought when I got better at it! My entire desk is full of crayons, markers, colored pencils, chalks, oil pastels and paints! 
Have you ever seen the how to blend and shade video by colorIt Support? It was posted on October 24,2018 
I have not seen that one yet! Is it very informative? I am always looking at ways to learn to improve even more!
Very. And they sell coloring books that come with a 30 day money back guarantee. Do your books come with this? 
No they do not! I didn't even know that was a thing. I thought once you color in them then they are yours forever.
You should look into it! Have you ever sold your drawings? 
No, I don't think I could make any money off of selling coloring pages.
