Week 7 - Directed study on various materials

This drawing took about 50 minutes. It was supposed to compare the different materials in the setup, but it turned out i'm very bad at comparing the materials of fries, bread, metal and the material of the burger box(not sure how it actually is, nor how it's called).
In terms of composition, i was trying to get the objects to overlap just enough so they don't cover each other, but also not to "kiss", i wasn't aiming at putting something in particular at one of the-rule-of-thirds points.
Another thing i payed a fare amount of attention was the shading of the objects. I tried to represent the volume and the curvature of the box as best as possible and i'm relatively happy with how it turned out to look. Also, i tried to over-express the stripes on the can's surface. But, as i mentioned, apart from these two things, i'm not very happy with the materials i tried to show.
Another thing i did was i enhanced the perspective just a little bit. This covers both the box and the paper bag for the fries.
