photoshop exersice 2

First I saved a picture of man and dog, and I pasted it into Photoshop. I used the rectangular marquee tools and lasso tool to select a man and dog, to make a vector mask. After selecting, I put new layer and I made it red, and I putted the picture of man and dog on it. And I hardly erased the side which has a different colour. After doing that I used the magnetic lasso tool to select the man and dog to put on the back ground of the forest. When I put it on the forest I had to use transform (scale), because if the picture was too big it wouldnt fit into the place. And made it look good and real.
