Week 2- tonal Practice during work 05/10/13

In the spare time i have during work i was able to have enough time to draw  Two quick five minute studies of tone on varies objects around me such as a mug and a stapler. i found it difficult to draw shiny surfaces such as the stapler being all black i tried to pick out the darkest areas. the mug was a little bit easier to draw picking out the highlights and is an easier shape to tone. More practice into tonal studies is  needed to improve on my existing skills.
