Below you'll find an example of the difference that craft makes. I took an ad and removed some of the finer touches. I went in and took away the little things that I've been bugging you about.
Notice how giving the background just a bit of texture changes things. Check out the reflection on the product - it's subtle, but nice. And the biggest thing, obviously, is the type. The original ad includes type that was set with care and purpose. The copy in the revised ad is boring could have been typed with by a monkey on a typewriter. A really smart roller skating monkey who smokes cigars, but a monkey nonetheless.
