Haha, I really like that little sparrow too. Drawing birds is so much fun! And yes, I definitely have *some* "classical" training. I've taken summer and Saturday morning art classes at the Columbus College of Art and Design and I recently took a figure drawing class from a professor of art at American University. (Along with high school art classes and the like.) Hopefully I'll get some further instruction while at college.
So here's something else. I thought it'd be fun to do a "Before and After" drawing. The one on the left is from January 2011 and the one on the right is from August 2013. I must say I'm pretty happy with myself.
