We own a different license but on occasion are involved with charitable givebacks and last week built a new forum for Zidisha.org which was formerly using Beehive to host their forums. We are HUGE supporters of XF and felt comfortable to launch their forum with the current RC2. We tried to emulate much of the look and feel of their parent home page.
It's a good start. Liking the node icons and the simplicity of them so nice work with those. However, I feel you still need to rid the xenforo default colours and work on the style more but judging by what you've done you have a potentially nice theme in the making.
