SHAPE YOUR SELECTION
The size and shape of your initial selection plays an important role in the fill
If you want to generate a specific object, the shape of the selection you make can have a huge difference on the look of what is generated. So rather than simply using the Marquee Tool to drag a rectangular box, try using the Lasso Tool to draw a freehand selection that roughly fits the shape of the object you want to create. Be specific about what you want to include in the fill. In this example, the first attempt to create an aeroplane was made with a simple box selection; while in the second attempt, we used the Lasso Tool to draw a rough plane shape at the angle we wanted, which gave better results.
