working on a new pet portrait (5 dogs) plus sales flyer

I'm currently working on 2 jobs this week. A sales flyer for a local business and a pet  portrait of 5 dog heads that will be a birthday present.

The finished size will be 11x14 - it's the first time I've done so many at one time. I'm using Canson Mi-Teintes pastel paper in one the speckle-tone-colors. since each of the heads will end up being kind of small, I'm using just pastel pencils, instead of pastel sticks as I normally would. Here is what I've accomplished so far. Comments are always welcome.  :)
