Repetition photoshop pictures

For this picture i used the gradient tool twice to make the pattern of the stripes crossing.

I didn't use the gradient tool at all in this picture but i used more contrast and exposed it more.

 

For this picture i think that it is obvious that i added a rainbow to the bars to add the extra colour.

 

I added the circular blue colour and i think that this picture now looks like the bottom of a pool.

 

I added a colourful ring to the red solo cups to make it look cool.
