1. KEEP YO PENCILS SHARP!!!
A sharp pencil vs. a dull one can mean the difference between a sharp, in focus drawing and a blurry one. Always have a pencil sharpener near by and sharpen your pencil often. A mechanical pencil is a great alternative to a regular one because they are always sharp!
2. KEEP YO ERASERS SHARP!!!
A sharp eraser will help you erase very specific lines, invest in wedge, Brick or disc erasers. They will stay sharp longer and are often better than the eraser that comes on the pencil!
3. USE YOUR WRIST TO DRAW A SMOOTHER CURVE.
Draw smart when making curves, use the natural tilt of your wrist to create smooth curves, and with some practice, it will become second nature!
