Popping around from street to alley with my plein air mobile/bike i can get these neat scenes that you cant get driving around (and walking is too tiring). i can tell that my three days of drawing gave me a good accurate drawing on this one. it has a lot of elements but the drawing went very smoothly. i'm going to stick with this sketching habit! its easy to stick with something that makes painting out on the street easier. give it go and see if you dont agree that its the best thing you can do for your painting!
