An office space would demand a completely different sort of wall decor
. It would be better to keep the wall hangings to a minimum in the work space. A simple oil painting or water colored landscape should do. Again, this depends on what sort of office it is. For mainstream offices, the colors should be neutral and the wall decor must not be distracting. An advertising or film office can, on the other hand can afford to be more colorful and artsy.
