I decided to further relax the restrictions I place upon myself for my daily sketches but I felt that the changes were minor enough that I didn't need to start a new named series. I used two or three different brushes while doing this one, and painted with whatever shades of the greyscale spectrum I wanted to use. The only restriction that I'm sticking with now is the one hour time limit.
28 minutes, referenced from a screenshot of my character in Skyrim. That's my new Dragonplate Armour. I've spent quite a bit of time at the forge in recent days and now my smithing skill is at 100.
