I've created three different cover images for each slogan and I added some elements such as rockets, parachutes, and plus signs to express the meaning of the slogan and make them more funny.
I also keeped the color theme that you mentioned: red, gray and white (I think black is not appropriate)
I hope you like my concepts and they are what you want, a winning images.
If you would want me to change something feel free to contact me anytime.
Thank you for your time!
