Looking good. Just watch out for your colour theory. Try not apply your colours randomly. Ask yourself:

* In what way does the brown used for the breadcrumb relate to the brown used for the thread list? What is your theory here? Why would the sub-forum list therefore be blue? (shouldn’t the sub-forum list relate to the breadcrumb better, since they are directly linked?)

* In what way does the use of blue define the purpose of the colour? What is the difference between the blue highlighted buttons and the title bar?

* The use of grey-on-yellow does not reflect the use of colour matching elsewhere. Perhaps the text boxes could just be an outline when unfocused, and get a colour when focused (or vice-versa)
