the shading unit was fun and i have learned alot on hoe to show all 9 value to make thing look 3-d . for the unit we used oil pastel and a app call "layer pro". with the oil pastel it was hard to blend the color together .but on the layer pro it was easy to blend the color right . i think my art work on the layer pro is alot better than the oil pastel .technology and art goes togetheris the major thing on earth . art makes TV shows ,movie and more things we like to see.
