Interesting, and I even like the name.
But... when I click on "Let's do it" under "Build your Website," nothing happens. This appears to be because what you need to do next is already on the screen: select a template.
So I would replace "Let's do it" with "Get started by selecting a template below." Currently, it looks broken (especially since clicking on "Let's do it" under "Name Your Business" DOES result in something happening).
Also, after selecting a template, the grid of templates disappeared and the bottom of the screen was replaced by a bunch of other elements. It wasn't clear at first that this was an example of the selected template, because the grid of templates disappeared (and was replaced by a smaller line of them). I thought I might need to interact with this large pane of items to proceed.
I suggest keeping the array of template thumnails consistent at all times, so when you click on one, the entire screen doesn't change; the example simply appears. In fact, you should probably start with the first template highlighted and the example layout shown (with an arrow or other indicator pointing from the template thumbnail to the layout).
Also... because the example layout fills the entire bottom portion of the screen and sometimes appears to fit perfectly, it's not readily apparent that you proceed to the next step by scrolling down. At first I was looking for a "proceed" or "next step" arrow. Reducing the example layout in size and confining it to a defined area on the screen would let you make navigation through the steps more clear. You could also let the user select different devices for the layout preview, and simply change the shape of the confined area instantly to show the layout on the selected device.
And finally: Is the download button supposed to work? It doesn't do anything for me.
