Tonal Values

During the class,we had learnt about the basic techniques of tonal rendering for sketches which included hatching,cross-hatching,scribbling and stippling.After the class,we were asked to take a picture of 5 items that we had.We had to draw according to the picture we took by using those rendering techniques.I had applied hatching technique for my drawing.Maybe its my first time trying the drawing by using rendering techniques,the final result of my drawing does not look good.So i had redo a new drawing by using the hatching technique also.During this task,i had improved my rendering skill and I knew how to differentiate the tonal values.

The picture below is my first drawing for this task:

The picture below are the drawing that i redo for this task:

The differences between the two drawings can be clearly seen when the drawings were being compared.
