My iPad Shading Drawing!

This is my iPad shading drawing. As you can see i used different shades of pink and red to show that the object is 3-D. I stated where my light source came from by the white spot showing a sort of glare on the object. By blending all of the shades of red and pink, it makes the object also look 3-D. I also blended the sky to show it was in fact a sunset. I used green hills to make sure the object did not look like it was floating. I am sorry for not having all of my objects, or even the shadow of this one, for i did not finish in time. Thank you.
