Creating beautiful line quality is also something that can take your drawings from good to incredibly awesome.
Here are three things to keep in mind for better line quality.
Keep your lines confident.
When you are drawing try not to scrip-scratch around figuring out where to put stuff. Draw a continuous, confident line instead. You can always erase it if you don’t like it but when you finally get it right, it will be a beautiful thing to look at. Often, when I am drawing, I draw light lines that help me figure out where to put the finished lines. The light lines don’t show in the end and altogether you get a better line quality.
Use line thickness to indicate form.
Thicker lines look closer to the viewer. Thinner lines look further away. If you are drawing a character with one foot behind the other, make the lines on the front foot ever so slightly darker than the lines on the back foot. It will give the character more dimension. It is the same if you are drawing a still life, buildings, or pretty much anything.
Line thickness can also indicate light and shadow. If you use thinner lines on the light side of a form and thicker lines on the shadow side you can show light and dark without using value.
Watch your edges.
This goes along with #2. However, you can take your line a step further if you give some variation to your edges. Just because you are drawing with line doesn’t mean you have to draw every little thing. Give the viewer’s mind something to do by creating invisible lines. An invisible line is a line that isn’t drawn but your brain fills it in anyway.
An example of this would be to imagine you are drawing a tree full of leaves. You don’t need to draw every leaf just the right amount and your brain just believes the rest are there. This idea can be taken even further. You don’t need to draw every branch or even the whole outline of the trunk. Just give the right amount of “tree trunk” info and the viewer’s brain will do the rest. This is a good way to get the viewer participating as they view your drawing, and it’s a principle that can be used when drawing anything from a person to a mountain.
Here is a short video I’ve created to explain these ideas a little more in depth.
