So far I have done only "reality" drawings on my iPad. That is, portraying only things I am actually looking at, whether landscape or buildings or interiors. But my attempts at depicting buildings continued to look messy and imprecise because I did not have a "ruler" to draw straight lines. But lo and behold, in the controls for Autodesk Sketchbook Pro, I found a tool to draw not only ruler-straight lines, but frames and blocks and circles and ovals as well. So now when I draw a window, I don't have to draw the frame free-hand unless I want to. I want to draw things that look like what digital master artist Robh Ruppel draws. His architectural scenes are amazing, and at least some of them are drawn on an iPad.
The window you see here is in the music room of my parents' house, over the piano. This used to be a really nice room until it became jammed with my father's hoarded clutter. No one can do anything about it now. You can see overgrown foliage and some fall leaves out the window. The fall colors in New England this year were surprisingly dull, due to heavy rains in August and September.
