Sent off my Surface Pro 3 for replacement today, finally. I stalled on that for weeks as I prepared my older computer to replace the Surface for a while. I got most of my work done in my sketchbook today, but I did manage to get one set of Croquis done on the Surface shortly before I sent it off. Waiting for my onedrive, dropbox and other services, apps and drives to finish synching so I can post the fruits of today's labor. Updating later today.
Today's background tests were focused on reinforcing something I learned about two point perspective during the beginning of the month -- apparently the two vanishing points should have a right angle relationship to one another from an imaginary center line in the picture plane. It has taken a lot of practice for me to begin to wrap my mind around this stuff!
