I'm hoping the forum pros can help me out with this. I've drawn a family member's corgi standing on the pier (done from a photo I took of him at the lake cottage), but it looks unfinished. I'm not at all good at drawing scenery and would like to draw water in the background. I'm not sure how I expect anyone to show me on online

, but maybe someone can post pics of a couple of visual steps as to give me the general idea? Thanks in advance!
