Just follow all steps of this tutorial and your drawing will be perfect:)
Some Things To Keep In Mind…
These tutorials are only here to guide you. Your drawing does not need to look "identical" to mine.
Start with rough but light pencil strokes that you can work into the shapes you want.
Once you have your rough drawing completed, go over it in a darker stroke for your final drawing.
Add shading and/or color to complete if desired.
Using this technique you will be able to draw anything after some practice... even without following step-by-step tutorials.
