What art program do I use?

I use Paint Tool Sai

Pictured above is my computer monitor's view of what I have been using since I was 13, Paint Tool SAI.

Paint Tool SAI is a high quality and lightweight painting software

I use a Wacom Intuos drawing tablet + pen to complete my artwork. Drawing lineart in black, then coloring it in using the color wheel and many layers.

Creating Digital portraits

My digital portraits are done all on SAI using many layers and sometimes many colors. I find it's software to be simple to use, and I am familiar with it. With Paint Tool SAI, I am able to create brushes that resemble clouds, hair, markers, and even blood splatters. With it I am able to blend colors seamlessly, and create bold lineart.
