I'd like a unique book cover design for a coloring book we are making for adults. The book cover is for an 8.5"x11" book. I need both the front and back cover created. We will want to include some text about the book on the back cover so there should be room for that. It will be less than 100 words.
1) The title is:
Adult Coloring Books: Swear Words That Will Make You Sh*t Your Pants
2) A swear word may appear on the cover, however it should similar to some of the examples included.
3) I'd prefer the background be in black or white so that the picture and color "pop" off the page more.
I've included 4 example covers that I really like. Something similar to these is preferred.
Updates
Project Deadline Extended
Reason: I've had a designer ask if we could extend the deadline. I'd like to get as many options as possible since this is a guaranteed project. Please extend it to Friday, February 19th, 2016. I may choose someone before then, but I'd like to see as many as possible before I do.
Thank you,
Justin
