Adobe Photoshop Practice (Spiderman)

Recently, I went for the 'Adobe Photoshop for Beginners' workshop. Using the pen tool to crop and clone stamp to fix unwanted images in the background, I tried merging my face with spiderman's body. The head looks slightly magnified. I was thinking if I had magnified it further, I could make it look like a baby spiderman. Nevertheless, when I posted this picture to Facebook, it makes my friends laugh.
