Affinity Designer is $50 one-time charge, whereas Creative Cloud is $50 per month. (I hate what Adobe has become). Affinity is the way to go if you want to make stuff like I do. If you want to make @steemitadventure's type work, first you need written permssion from him. Then you need either Autodesk Sketch or Corel Painter.

But a pencil and paper is the best first step. Get to work and start drawing tooth-themed art!
