Nice, but few minor alteration suggestions:
- The titles have those extra bits around the leeters (like a shadow) that look not so nice, so could you edit them out.
- Back cover's title goes out of the gray bars which again is minor imperfection (try centeringit so there is same amount of gray bar visible also on the right as there is now on the left).
- Back covers Eniox logo should be 5mm or 1/5" to the left to make sure it does not go to spine when printed.
The back text is big blurb of text, dividing iot in to paragraphs would make it bit nicer read. (also not big fan of center alinged text...).
Thank you for the cover.
Just wish the logo looked more like the one Dynamic Designs made.

However I could not reproduce it.
True.
And beyond my skills as well.
