My technique and style have evolved over the years due to changing software and hardware. My early works were inked and colored in Photoshop with a mouse. After that, I started to use Illustrator to ink my work more smoothly to then move over to Photoshop to color. Nowadays I'm currently using Sketchbook Pro on a touchscreen tablet with a stylus. I still use Photoshop from time to time for finishing touches.
