My First step was to copy the man by using the free select tool. I then dragged and dropped him into a layer. My next job was to use the free select tool on Big Ben. I then copied it and dragged it into a new layer.
This is what the layers, in the end, should look like.
I then used the clone tool to copy the background of the image where I got the person from. I then used a large brush of the Big Ben to fill in the sides of Big Ben with darker clouds. Afterwards, I used the smudge tool to help the clouds to better blend in. Next, I had to adjust the person’s size via unified transform tool. My next step was to use edit the brightness and contrast so that the person doesn’t stick out as much.
