Reflective Surfaces - Light, Reflection and Refraction

This is a directed study of practicing on different types of texture. This drawing is very successful on portraying the shapes of each objects through the shading. The value of the light and dark is just perfect to preform the contrast. The texture on the objects can be identify very easily. The best one on this picture is the glass, I did well on both reflection and refraction, the image perfectly shows the transparency. And I was also successful on building up the metal texture on the tiny can, showing the detail of reflection on the shiny surface. Other reflective objects, like the ceramics cup, plastic and the art eraser are not bad. The contrast of light and dark on the rifts of the art eraser and the folds on the fabric are presenting quite well. I disappointed with the box which at the top left corner. The shading and form are fine, but the outline is too strong, it makes the box less realistic.
