Use the character and environment designs you created in the previous lessons to come up with a compelling composition for your key art. You can make this look like a movie poster, a widescreen image, or any format you think works best for your illustrated property. 

Choose whichever key art design you like best, clean up the linework, and begin to ink the outlines. Though Amin does this on paper, you can use any traditional or digital method you prefer for this stage. 

It's helpful to create a lighting reference at this stage. Amin chooses to build his in 3D, but you can also take photos of friends and objects with your desired lighting, or use nicely lit photos from the internet when making your piece. 

Once you have your outlines done, you can start adding shapes into the image. These don't need to correspond to specific values or lighting (which will be covered later), they just need to be different enough to overlay various colors on top of them in the next chapter.

Using your newly created reference as a guide, add color and lighting to your key art. To start, you can simply apply colors to each one of the value shapes you created earlier. Try to use a compelling color palette to ensure your image really stands out.

It's time to finish your main key art for the course. In this stage, after taking another look at your image, you'll do any extra steps needed to bring your image to completion. This might involve changing the colors, adding details, or even altering the composition. 

Try adapting your main key art into new formats. This is a very useful skill to cultivate for the modern of world of art creation, as your project may be shown in different ways. Your new images could be widescreen, tall, square, or whatever sizes you choose.
