This painting is an example of the element texture. Texture can be physically felt or it can be implied which means cannot be felt, only be seen. You can't really feel how smooth the apples are but the highlights make the apples look smooth.
colorful and kind of minimal graphic design/illustration work by the 15 year old New Zeland Jeremy Young. For a 15 year old with this kind of details and creative artwork, I’m sure he’ll have a rich and successful future.
