Add design and color work to PDF documents

Hey there! I have a number of PDF documents that I would like to add color and design to in order to appear more attractive to readers. The extra color and design work should "smarten" things up a little. These PDF documents are essentially "game sheets" and are mostly text except for a diagram drawn at the end of each game. There are a total of 100 PDF documents. The theme is "Icebreaker Games". That being said, this is not a particularly complicated design project by any means. This is simply an attempt to spice things up and make it easier on the eyes. Thank you for your interest and feel free to contact me with any questions. P.S. 3 files are attached. "Star Wars Original" and "Star Wars (3-6)" are PDF documents from a previous project. They are the before & after. This is exactly the type of changes that I'm looking for to be made in the PDF document "Secret Leader". P.S.S. I've also attached the app icon for your convenience. *IMPORTANT* The size of the new file should not be much larger than the original file. For example, the size of the attached file is 137 kb - it should not exceed 50% of its original size (50% of 137kb = 68.5 --> New file should not be larger than (123 + 68.5) = 191.5 kb. Just try to keep the new file size as low as possible while adding "some" graphic/design layout". Please, with your bid, download the "Secret Leader" attached file and send me back the same file with your graphic/layout changes. Thank you.
