Well, here is a book cover itself. Thanks for the suggestions on Moodle.
I wanted to make it look close to the 60s time; that's why I chose these colors. As you can see, the name of the book and the author are painted in hippie-kinda patterns, and I used my drawing of Bob Dylan there. I didn't want to add too many pictures, drawings, and models, so the cover could be kept simple.
I've added everything I wanted on the back side of the book - it's a FREEWHEELIN' album cover, acoustic guitar, and a book description.
Your comments and suggestions are very welcome!
