Gradients

For the sky in the background of my poster, I added a gradient because the original poster had a blending background so I thought a gradient would be the most fitting blending method.
To do this, I made swatches of all the colours I needed for the sky, and then used the gradient tool to fill in the selected area with a gradient.

These are the settings I used for my gradient. I have three different colours blending as there were three main shades on the original poster. I also changed the angle of the gradient to it looked similar to the original. With this effect, I think that it makes my poster look much closer to the original and fits with the style.
