I'm simply wanting to know if tracing, outlining a picture is ok when selling art. An example : I took pictures of lighthouses I visited and wanted to get to the painting process rather than spending a lot of time drawing the proper perspective of the buildings, etc. So this way, I skipped that step and worked on the style of painting that I preferred (although, for me, every painting is "practice" and learning). Some details were unlike the picture such as adding clouds and making it a sunny day rather than overcast. Sorry for all this detail. Please advise! Thank you, Carol
