For this photo, I did a lot of photo manipulation. The mountains were purple, I rendered out Donovan Mitchell, added a few adjustment layers to him, including curves, vibrance, etc. Then used the brush tools to add the color dots around him. The background has been adjusted as well, using the clone stamp tool, the color adjustment, etc. The text is a retro style text made with various styles (emboss, Inner glow, drop shadow.) The pictures I modified are below.
