Description: First step. Study the guy that you want to caricature. Look out for key features that can help you exaggerate. Of course look at a couple more reference pictures to aide you because different pictures will allow you to see different features. For example, in this picture he doesn't seem to have a very long neck but other photos of him show off his neck long neck. Almost as if he were a giraffe.
Description: I remember my idea sketch and start by drawing his eyes. I look at the reference from time to time to help me find the flow of his eyes. One thing I noticed to help finding the shape of anyones eyes is to block out the iris and pupil. Just imagine the whole eyeball as negative space. This will help you concentrate better on the way the eye is shaped.
Description: Now I use a different color for the lines now. It gives the caricature more of a cartoony feel. I still take in mind on how his nose is shaped. You can see in the reference picture, he has a bulb in the middle of his nose. I also exaggerate the length of his nose.
Description: Here I just concentrate on his chin. Using anatomy will help. Always picture there is a line flowing down from the wings of his nose to the corner of his chin. This will help you find out where to properly place the chin.
Description: Here I draw his ears. When I look at the reference picture, I find the flow on the outside part of his ear. Then I work my way inside. Always work outside to in for ears. This gives you the sense of shape of the ear. I also add in his thick eyebrows that rest almost right on top of his eyes.
Description: I add his iris and pupil now. Always alternating at this part. I start with the pupil on the left side and the move over to the right eye. Then do the same for the iris that circles around the pupil. Alternation will help you have things level and consistent.
Description: When I color this I use the lightest skin tone I can possible then get darker with a tone for the shadows. With the different colors of lines and the color filling the face, it just gives the caricature a great cartoony look. You can also see that I added his blue/green highlights for his hair. And then WAH-LAH! A caricature of Josh Ramsay.
