Q&A for How to Draw Clouds

There are erasers that either don't erase well or are specifically designed for smudging. They will produce similar results to smudging with a finger. Smudging erasers are found in art shops.

Use different shades of grey and white to make your cloud more realistic.

Shade very lightly, and constantly erase and redo.

Compare your drawing with the model and see how you can improve. Keep practicing.

Yes, you can. As long as you don't press too hard as you shade around, it would be fine.

You just do the same as above, but instead of drawing the curve, you draw a straight line.

Yes, I suppose you could draw a camel hump, then one slightly sideways, touching that one, and around in an oval shape. Or, you could do humps in an oval shape as if you were doing an oval flower.

With practice, you should be able to draw clouds without making ovals. Instead of actually drawing the oval, you could visualize it.
