This pen uses the zoom feature!
Set your maximum size, and as you zoom in and out, it’ll adjust the output size accordingly. VERY handy when working with variations in line weight. Sketching, line work, details, filling, it can do it all! I have a shaky hand so stabilization is set to 30, but stabilization is set in the quick settings tab so please feel free to change it as needed.

This illustration was sketched, lined, and colored with the snail/slug pen family and default tools. Only the background is a special asset :)
Update: Over time, I’ve slightly adjusted this tool, so I’ve changed to the most recent version.
