It is my first time setting up a website on Drupal and Hoa has been very helpful in creating a great corporate site.
On the theme itself, I find it very powerful as it provides many options and layout. The abundance of options also means you will have to explore as I don't think the documentation is sufficient to see you through by yourself.
I suggest you install the demo as well. This will give you a great idea of how things work and where the elements are.
