The result after keeping the background and the foreground in mind will determine how the background and the foreground complement each other and shows your drawing at large.
This oval is just for your reference as to how much space a part will take and within this space you must encapsulate the specific part. You may erase these ovals and lines when the actual parts are ready.
With this you are ready to start with the features and detailing like the hair, eyes, nose, lips, beard and so on.
Make the hair strands a little below the shoulders. Jesus’s hair is a little longer than the shoulders.
You may make guiding lines for the eyes, nose and mouth as per your convenience. Make ‘u’ shaped pupils inside. A perfect circle for the pupil gives the appearance of surprise or shock. A ‘u’ gives a calm appearance. Once you are done with the eyebrows and the eyes you may make a curved line for nose. There will be two curved lines at first. First will be the long line for the length of the nose and the second will be the smaller curve to complete the nose.
Around the lips make the mustache and the beard but very lightly. The mustache could be shaded vertically while the beard could be done horizontally. The beard will start from the lips and extend to till the ears. Then you may draw the beard long. The beard appears like a triangle pointing down. But it is not a perfect triangle. Remember, a little difference in the features will not be a big problem if you are planning to outline the drawing later on. The outlined image looks different from the sketched one. The image changes appearance even after coloring it if you plan to color it later on. Also for the hands you may make two ovals at end of the arm. Later you could create fingers which will be curved upwards. Remember to make the fingers slightly pointed at the end and thicker where it starts.
Make the scarf on top accordingly. To make it look more appealing, draw extra lines on the clothing to show folds on the garment.
The shading or the pencil strokes are darker and thicker when there is a fold. Eg. On the robe where it is folding. You may also shade darker at the end of each feature to make the features stand out. You may hold the pencil or color you are using gently while shading. This will help you in increasing and decreasing thickness and intensity of the color too.
After you outline the complete drawing of Jesus you may erase all guidelines of the pencil.
