Hi is it ok to ask for advice for the challenge? I am painting this photo of an old castle 20 minsutes from where I live. I will cropp it slightly. I don't know why those ugly modern buildings were built there as they are an eyesore. Is it ok to paint the scene by performing a " building ectomy" and remove ( without planning permission) the offending things? I have about half of it done, leaving the buildings till last.
