Start with drawing the posture of the character.
use lines and circles to draw the basic posture. If you find this hard, use pictures or action figures as reference
Then, draw the body of the person according to the 'Lukisan Lidi' you've drawn earlier. This is the part where you determine whether your character is muscular, slim of fat.
Then, give him personality (hair style, clothes, trouser etc etc. Refer to fashion magazine of any pictures for ideas on what clothes for your character to wear. As for this one, this character wears nrmal t shirt and jeans.
Using pen, outline the initial sketch. Outlining needs a little experience to come out with a good result. Experiment with different type of pen to get the best result.
Tadaaaa! a gay looking happy person. hehehe
Try experimenting with different posture and different apparel.
