Proportion and Depth

I continue to be inspired by the amazing sketches on Urban Sketchers. The different styles of recording the world these artists look at are all equally enticing. Not only am I travelling the world, but I am trying to imbibe (if that is the right word) the techniques and the quality of sketching with the intent to bring my sketches to life.

After looking at my quick sketches I have noted that I need, firstly proportion, and then depth. I seem to start out with one size subject then everything around it loses its proportion and makes it into the picture as well! And I have difficulty separating the foreground from the background.

Have a look... see what you think.
