I am a great drawer, but I cannot draw microfigures! You may think that because I am young I won't be great I really am, but I need help drawing this, on paper.
Since you'll be working at a scale you may prefer to use graph paper. You can print your own if you don't have any, this will make it easier. Use a ruler, pencil and a rubber to draw your microfigure.
A microfigure is roughly 2/7 legs, 2/7 torso and 3/7 head high, It should also be 3 squares wide. You may find the diagram below makes it easier to visualise:
At this stage the most important thing to concentrate on is symmetry.
For now, concentrate on the vertical symmetry (top-to-bottom). In my sketch I've drawn out the three boxes first and added a few rough outlines within the guidelines. These guidelines can be erased later when you have finished.
If you can draw Microfigures, you can draw Minifigures. All it takes is a change of scale.
Take a look at:
Personally number 3 looks like the best bet to me.
