I thought it might be interesting to show how I do an oil painting. Since it is summer and I have a lot of reference photos of sailboats, do not own a boat:( , but we have Lake Erie. This is my basic drawing of the painting. If you can not draw, take a digital photo of a boat, print out the size you want, grab some graphite/carbon paper and trace the image. Note your value plan, dark areas, light and medium areas.
