This is a hair's breadth away from the trash can, but I thought I'd show it anyway, if for no other reason but to remind myself what not to do in the future.
I will redo this painting of my mother, as the watercolours just weren't working for me. The muse was off doing other things and she obviously was not guiding my hand on this one!
So what is it that makes us know when a painting or drawing isn't going right? A drawing that is off is one thing, but often I find it is values that are lacking, or simply the vision that is in our head just doesn't appear on paper or canvas. Or fatigue, lack of inspiration - the list could go on and on to help justify why what I want to do doesn't turn out as I want it to.
I also accept that not everything I do will be pleasing. I haven't calculated numbers of drawings and paintings, but should for perhaps a month to see what I think works and what doesn't. If I note time of day when I draw, mood, weather, level of fatigue, and the other things that all seem to feed ability the create, perhaps I will see some pattern emerge that leads to success or failure when creating an image.
I'll let you know the results when I figure out just how to analyse the process.
