Hej Chris,
this looks good and i think it'll work pretty well. but, i'd like to draw your attention on a few things. First, purchase buttons seem to be quite colourless. they're not attracting.maybe making the corner sharp rather than round and/or using vibrant colours could solve the problem. the green colour of the price is really boring. second thing is that the alignment of items under Things You Will Learn could be left instead of center. As it is now, it looks un-professional. Last of all, it might be a good idea to present some brief information about the authors somewhere at the bottom or in sub-pages.
good luck.
Maybe you should take a picture of the book or Photoshop a 3d-book of it. It would really stand out as the rest of the design is 2d.
in the right column "things you will learn" presently its center align it will be good if u make the text left align as everywhere u have used text as left align..
I am immediately hit with confusion. Perhaps the book title could be more dominant and the call to action more closely associated with the specific goal.
I like the color scheme and it is a clean page, just not deliberate.
The headline 'Get the Book!' should be replaced with something catchy about the book, for example 'Learn WordPress In Easy Way', something like that.
Also don't forget to list benefits of the book instead of features.
Hope that helps.
I think you have a good design here but it could benefit from some detail work to make it more exciting. Whenever you use a dark strong with a drop shadow like you are here, it seems to blend together and makes the stroke look like it's feathered. I would maybe use an off white stroke. Think about putting a subtle texture in the background as well to liven things up. Overall this looks good, stay the coarse, just modify a few things.
Try making it more glossy, glow, emboss the text there - right now it looks really boring.
Also, the text paragraphs could use a little more space between each other.
