the white image looks really good!
I think the beam/truss will either cause the paint/plaster where it goes through the wall to crack and possibly also make the plasterboard come off from the framework. Hope you dont get earthquakes there!. aesthetically it may have been better to split the wall where the door is or make everything from the left hand side of the door to the right a framed glass wall where the beam passes through some kind of flexible bracket in the framing. Still its a bit late for us to comment on this i guess and no doubt cost was an issue!
For the coloured image, it looks like you have used standard materials?. Some people I work with insist on doing the same and they never receive shadows properly. Overall its starting to look better though as you work on it more. cool office as well other than that beam which would freak a lot of people out
