My Shapes created using Photoshop

I made this picture using Photoshop elements.First I changed the background layer to black using the fill bucket. Then I made a new layer for my circle and to make the circle I used the marquee tool. Then I used the marquee tool and made a square using another layer. I again created another layer for my triangle. I used the lasso tool to make the shape. Then for my blob I once again created a new layer for my blob. Then I used the move tool to move my shapes around. After I was done I used the layer effects make my shapes look better.
