My second oil painting I made back in high school. I used Walter Foster's Ocean Sunsets book and found this pic so I followed the steps and this is how it turned out.
Back then, there weren't any art tutorials online nor YouTube videos so if you want to learn how to draw/paint/etc., your best chance is either Bob Ross(painting) or buy/borrow how-to-draw books like Walter Foster's.
I still own some of them today as I'm planning to use them again and wanted to go back to do traditional art again.
