I made this guide/tutorial partly for my own reference, and partly for anyone who does wonder how I go about coloring in Paint Tool Sai. I figured I oughta share it with you DeviantART peeps. I hope it'll be of some use, maybe!
Yeah, sorry if my handwriting isn't excellent. Sure, there are better ways to color and shade, but this is just how I do it. If you have any questions I'll always be open to try answering 'em!
