I am Manuela and work as Digital Illustrator from Italy.
I can create beautiful and professional book covers.
Book covers can be totally different, it depends on what you need.
Some examples are:
1) Just text cover
2) Photograph Cover
3) Illustration Cover
I will send you a little brief to understand what you need.
You will become front and back cover.
You can get a .ai or .psd file, it depends on how I work on it.
