personally I would change it to a more reassuring dark brown because brown is associated with order and being reliable
http://www.squidoo.com/colorexpert keep the textures and apply them to all the windows you've got going on there (at the moment there are three different window styles none match) and replace that graphic I've seen it in every mock up and hated it every time, think it was used in either nemesis or mages of soma, any render just not that one.
oh and stay away from web 2.0 type graphics that are shiny and colourful if it's not relevant don't just add them because it's the latest web style, because any time now that fad is going to fade and it really doesn't suit soma.
something to aim for:
