My White Objects Painting.

In my white objects painting, I seemed to struggle a lot with making the shades of the objects more detailed and real. I really did try to make certain objects and things stand out, but it just was not my best piece of work I have made. I think I did well on the background part and the pitcher and the bowl I think I did pretty well in. But I think I could have improved on making the paper roll and the mugs. I didn't feel that I knew how to approach these objects in the painting that thats why it didn't turn out as great as I would have wanted it to be.
