I finished coloring in all the machines (i.e. cash register, candy machine, soda machine) with a gradient fill so that it would create more effects/depth. At first it wouldn't let me fill it in with a bucket tool so I had to make the shapes a closed figure with the line tool. After that, I erased/delete the lines I create so that you wouldn't see it and it wouldn't be in the way. Also because I didn't need it anymore. I also did the same thing for the cash/money and the octopus' arms/tentacles.
Then I continued making more popcorns for the popcorn bag. I had to use the brush tool once again to make the small outlines of the popcorn and fill it in with a light yellow color with the bucket tool. Then I moved it inside the bag a bit.
Here's a close up of the lovely popcorn bag.

Here's what I have so far....

Cody and Zach suggested that I make a layer ontop of a blue overlay to create an ocean look/effect. So I made that by using the rectangle shape tool filled with a light blue color with a very low opacity.
Here's what it looks like with the blue overlay stuff that Zach and Cody suggested.
