Paint Tool Sai BASICS

I have used Paint Tool Sai for about a year or so now to do all my digital art. It doesn't come with textures, like Adobe Photoshop does. And you definitely have more interesting features with Photoshop, but really, Adobe Photoshop is a glorified Paint Tool Sai. This program isn't really confusing at all! Its very clean and easy to use. Now, i have been looking on Deviantart (which is a website where artists post artwork) and I have found some tutorials on Paint Tool Sai. Here they are:

The tools i mainly use are...

• Ink pen (for line art)
• Pencil
• Bucket
• Brush
• Water
• Pen 

I don't really use airbrush, but I DEFINITELY recommend it for first time users.

I personally am HORRIBLE at keeping my line art neat, so what I do it double click the tool and set the two options that have numbers back to Not Specified. This makes the movement very slow and neat. And a lot of people will use the pen tool for the line art, but since I always set it to Not Specified, it gets really annoying switching it back and forth from Not Specified to 3 since i also use pen for coloring. So i just use the ink pen specifically for line art.
