1. Texture is extremely important to have in your sketches because it gives the viewer a more lifelike drawing that allows it to come to life. It helps the picture look real. It just makes the picture better in general when you use texture.
2.It is necessary to have several references for each animal and its background so that you can have different views of the animal. For example, if you want to know how the legs of an elephant look in detail but in one of the pictures the legs are covered with grass in one picture, you can find one where they are showing. You also need backgrounds to help you know what the backgroun of your picture should look like.
3. When I look at my pictures I am able to see which one is strongest and will make the best print based off the textures in the picture and how the background looks. I knew this one was the best because the elephant has a lot of wrinkles which makes for very good texture. Also, the trees and water in the background help the picture look real.
