The site would appeal to the average person because the colors are warm and inviting. When I first entered the site I could tell that a lot of thought had gone into making it an excellent one- I can tell that it has been worked on for a while and has been polished until the creator was satisfied. Someone with no technical background can easily see all this.
The layout makes you feel very comfortable, especially the boxed-in idea of the pages. The soft and warm colors and minimum text on the main page are great; a big chunk of text on the main page always freaks the reader out, which is not what you want.
Great job!!
