Rendering Textures & Perspective Drawings

Rendering textures kind of art are tough for me to draw and it is hard to get the shades right according to the objects and the textures on the above. well it took a few practices to hands on my skills and techniques.  Mr Han gave us the A3 worksheets with the example of the pictures and we just had to draw following the pictures and explore on how to draw the different textures. Overall, i gave myself a pad on my shoulder for putting all of my efforts to do and soon i will improve my skills and techniques.

In addition, the following 5 pictures on the above is my art works on Perspective drawings. I am exploring the vanishing points of 1 point of view and 2 point of view. The first four pictures i drew it on PVC materials of papers by using permanent black marker and framed it. the last picture i choose out of four perspective line drawings and paint it on A3 size paper as my final piece of art work.
