BOOK COVER

I am not sure if you need the thick and strong yellow borders on the back. On the spine, I would use just one type size. It will be great if you can get a professional illustrator to do the cover, if the budget permits.

or, you could try finding a suitable image from istock...
i would also use some other color instead of the bright yellow

i dont so much mind the yellow border on the back but i do mind how it doesnt give the text any room to breathe. at some points the border seems to be touching the text. bring it out a bit and see how it looks. i also suggest to lose the drop shadow, or at least take it to the same level that the 'Sheekooying Soomaaliyaeed'(on the front cover) is at. its too big and bulky and weights the back down.

The spine copy needs to be rotated 180 degrees, so that the book title is at the top and reads going left to right. Look at your bookshelves and you'll figure it out.

Also, the copy on the back is justified and creates a lot of bad spacing problems. Try it flush left, ragged right and it will breathe better, and eliminate all of those spacing holes between words -- yuck! And put some more space between the border and the copy (as others have mentioned).

Be sure to post an update.
