As you can probably tell by the title, the contents of the blog are pretty self explanatory. Every day Graeme Borland, a game designer/programer/2d and 3d artist, does a digital sketch. Every day. Like, seriously, he doesn't miss a day. He does this to strengthen his overall composition and conceptual skills. He's been doing this since January 1, 2012. Which means that at the time of this post, he has just done his 765th sketch.
If you follow him on tumblr, everyday he'll post an image of a digital painting along with what number it is. More recently, Borland has begun to create youtube videos of him drawing his daily sketches. I find these fascinating because they give you a glimpse into how he creates. I've posted his latest youtube video here, for you to enjoy.
Oh, and what kind of an artist would I be if I didn't mention that his website also has many fun projects that he's done, many of them gaming related.
