Hey mate. You need to work more on the typography and the positioning.

Other that that, great first try.

I can agree with ^

The text on the book is ugly. There is a perspective tool you can use to make it look like it has that depth, rather than just sitting there screaming our names.

Also, on the 7th box down, there is that annoying little circle that covers a small part of the 3 in 39.99

Serif fonts aren't too bad but I would only use them as headings and sans-serif fonts for body text. The bottom section looks slapped together. The leading is bigger than your padding. I would recommend making the padding twice as much as the leading.
