I began with changing the levels of the image to make everything brighter and stand out more.
I went onto the ‘indexed colour’ menu.
Then I reduced the amount of colours on the image from the original to 32 to make it look more pixelated for the final outcome.
I decreased the size of the image to 50 by 75 pixels.
Then again I changed the image size but instead increased it by 400%.
The final outcome.
