For this collage, I used two Pantone swatches and used duotone after applying grayscale.

 This was my first draft, and after printing, I realized this was not the direction I wanted to go in. The collage blends too much into the background and the colors are too subtle. The text was placed too close to the banner. Lastly, the title was too simple.

After my first draft, I decided to use a different image and color. I used duotone with two Pantone swatches I used the same green, but I switched my original brown swatch to a brighter pink instead to make the colors stand out.

For my final design, I applied an overlay to my image to make the colors more saturated. For my title, I applied a text warp effect to give off a psychedelic feel that matches San Francisco culture. I used purple as my background as when researching I noticed a lot of psychedelic posters use purple and it's eye-catching. Overall, I love how this poster came out as it aligned with more of my vision compared to the first draft.
