|1. Start with an oval.|
|2. Add the eyes/nose/ears guides.|
|3. Shape the head using our oval as a reference.|
|4. Add the facial features.|
|5. Let's draw that big ol' fireman's hat!|
|6. Finish roughing the final features.|
|See how it cleans up nicely?|
In fact, they might even hire a guy or gal to do cleanup... it was the cleaned up copies that were forwarded to the ink and paint department. Otherwise it might be too confusing for the inkers to decipher which of the rough ovals, circles and construction lines to keep.
Digital cleanup is basically the same thing. After creating your rough drawing you create a new layer and draw your final drawing.
Anyway I found this particular character to be a lot of fun to draw and I hope you enjoy drawing him as well.
