I have been asked before, but have never really had time to show how I approach my digital stuff.
Firstly...You can draw and paint digitally just like oils,or any other medium.All freehand with a Wacom tablet and...imagination
This example is very simplistic compared to my detailed stuff,however,I start all of my bigger works just like this.This took about 1 and a half hours.
What you need...A paint program,a Wacom
Open a new image...This one is 2000x2500(pixels).I would suggest staying 1500 or larger...
