Picked up one o’ them there artists’ mannequins (yeah, they really exist!), and am using it in tandem with my picture frame to study light and perspective.
Sleepily watching an old movie, and doodling to meet my quota!
Ah, you never know what you’ll find in Mark’s Sketchbook. One day, it’s a naked lady, another day, it’s office furniture. Just a little more pracitce with my gridded picture frame. It really is helping me maintain the proper perspective. Now I just need to acquire more interesting possessions.

I still struggle to get everything in the right spot on the page. I thought maybe I could help myself get over this hurdle a bit quicker if I practiced viewing objects through picture frame glass marked with a grid, and drawing on a Photoshop file or piece of paper containing the same grid. I think it works pretty well.

I thought this might be considered a crutch, but it’s actually recommended in a lot of art books as a way to train yourself to measure. Eventually, you’ll be able to gauge all this stuff in your mind.
Randomly picked someone to sketch. Why Abe? Why not? Heck, I might vote for him in the general election.
Tonight I toyed around with the idea of planes again, spurred on by this short lesson on CtrlPaint.com. This guy’s lessons are great, by the way, and cover the basics as well as more advanced stuff.

I’m not even sure if I did a great job finding the planes here, but just considering them was a good reminder that the head is a mass and not a flat shape, which in turn results in more believable proportions and shading.
