It is likely that you know about drawing the "base shapes" of your drawing while continually adding more detail. This is a commonly used method that will probably aid you.

This could mean drawing it in different styles or with different tools or from different perspectives.

a bedroom, a farm, or a school with kids in it. The possibilities are endless.

A common criticism is that "it has been done before". If you want to do something that has been done before, then great! Do it, make it your own, and improve. The only time this criticism is valid is when you create something "clichéd" for the sole purpose of gaining attention. (There is an exception to this: do not draw pornographic or violent material at school or a public institution.)

Draw in your notebook, on a whiteboard, in the dirt, with chalk, with charcoal, on the computer, with Photoshop, with MS Paint. Draw with your eyes closed, with your off-hand, or even with your foot (Warning: this is hard). Draw the same thing over and over again; it is your work, do whatever you want!

Believe in yourself. Go out of your way to admire what you like about your drawings. Do not compare yourself to others, only to your previous work.
