Well, I thought I'd try a sketchbook. I've mostly lurked here before. I've been a little timid because of the high levels of talent here, but I figured that if I'm going to improve myself I've got to get over it, hehe.
Here is a sketch I did from a photo I found somewhere on the net.
These are some studies from Loomis' book.
Someone told me to do sketches of celebrities since other people would be more likely to catch errors so I did one of Jensen Ackles from Supernatural. I see some errors, like the lips are too far from the nose and other proportional problems I think.
This one is a bicycle charcoal drawing I did in class last semester.
Finally, this one is an oil painting I also did last semester for school.
