Working with Digital Art Techniques
1. One way to get started is with a drawing tablet hooked up to a computer and monitor. You will have a surface to draw on with a wireless pen called a stylus. It allows you to have natural variation needed to achieve what you can not with a mouse. Use free software like GIMP, Krita and MediBang. Overall price/quality often comes down to the amount of pressure sensitivity and the brand.
2. Tablet or laptop that works with a pressure sensitive pen like an iPad with apple Pen or the Surface Pro. There are a lot of apps out there but you might need to run desktop software.
3. Go professional. Get a drawing canvas that hooks up to your computer or one that stands alone.
