What size should your image be?

If you are designing for video/screen – work to screen size ratios over paper sizes. For example, HD TV should be 1920×1080 pixels

Choosing Fonts

Creating depth in a composition

Where you apply light and dark lighting creates an impact. To instantly create depth the closest objects should be the darkest. The next objects back should be darker, followed by the third layer, which if created to be the lightest object in the scene will draw the viewers eye towards it. To make the key light pop, contrast it with a darker layer behind

The golden ratio

The golden ratio is a composition technique that refers to the idea that this particular mathematical formula is found commonly across nature. When this shape is applied to drawings – laying details to appropriately fit the shape – it becomes more successful. Here you can see how well it fits into the examples shown.
