I started this piece in photoshop using this photograph, copying three more versions of the image and flipping each one horizontally, vertically, and both at the same time, and positioned them together to create a mirrored effect.

I experimented with different blending modes for each blending layer and was left with very prominent yellows, with some reds and blues in the background.

I flattened all of the layers into one, sized down the entire image into my canvas, and centred it.

I then decided to copy and paste another version of this shape, enlarged the new copy behind the original, and centred it. I was left with this as my final image and I am quite happy with it.
