As you can see we have a pretty decent result so far. But what we are going to do with that white area in the left top corner? It is clear that we have to remove it. To do that there are several methods; you can pick the Burn Tool, Highlights Range and darken that area in the Original Image Layer or you can choose an even easier way. So, create a new layer just above the Original Image Layer and call it Dark Area Layer. Pick the Brush Tool(choose a Soft Round Brush, size around 70px, opacity 100%) and simply paint over that area. Pick a color from the image dark colors, for example #4c3e31.
