The green triangles round the edge of the image made the collage look to cluttered, so after getting feedback I decided to add a green glow instead. I changed the triangles to white and then lowered the opacity.

Using the paint tool on Photoshop I created some textures to add to my collage to give it more depth. I played around with the blending modes and opacity so that everything blended together well.

After looking at different optical illusions I wanted to incorporate something like this into my design. So I came up with my own design inspired by optical illusions and added this to the picture from my previous collage.
