Charcoal and ellipse

In this session on the 12/11/14 I had to choose which area of my work I felt needed more practise.  The areas I chose were using charcoal and drawing ellipse. I found a picture of a glass bottle on the internet to attempt to draw using charcoal.  The materials I used were a 2H pencil to sketch the bottle, an A2 piece of cartridge paper, charcoal and white chalk.  The techniques I used were sketch, scale, proportion, tone, shading and ellipse.  I think my charcoal drawing worked well and I can see an improvement on my ellipse drawing but still think I could improve on the ellipse.  To do this I will research ellipse further and practice drawing ellipse at home.
