Illustrative look and feel

Hi all,
I am looking for some advice on how to get a very different type of look on your 3d work. I have added some examples of the style and look that I am going for.

Does anyone know of any types of tutorials or ideas on how to approach this. Is evee or cycles better? any ad-dons?
I am asking because I am new to Blender 2.8

Thanks for the help

Alex
