Here is one of my current projects. This is the portrait of Sayer I'm working on for a Mentored Portrait project over at ScribbleTalk.
We chose to work on Uart 600 for this first project, one of the 7x11 sheets that come in the sample package from Uneeda Enterprises. (Thanks Tom!) Each sample is a different grit, 400, 500, 600 & 800. Our finished portraits are 6x9, with prismacolor pencils. We will be doing one on each of the sample sheets included. For those of you who don't know what Uart is, it is an artist grade sandpaper, available in different grits, just like you'd sand wood or metal with. Here is the link to the manufacturer where you can request a sample if your interested. http://www.uartpastelpaper.com/
We drew these out by hand, right on the Uart. You'll notice a bit of tweaking as Sayer progresses, from the beginning sketch to where it is now. Tweaking as I go is how I usually work, it appeals to the artist in me. Nothing is ever set in stone! Just because it may or may not be in my reference photo doesn't mean it has to be, or cannot be changed. Artistic license is a wonderful thing!
Below is where Sayer is at today. The tooth on my Uart 600 is getting full, which is what I want. It won't be much longer before this one is complete.
