I see nothing but red flags with this modification.

The trusses were modified. Any modifications to a truss requires an engineered solution, not a carpenter's experience thinking they are overbuilding for safety. (which they may not be doing)

From the picture I can't see what is supporting the cathedral side of the roof rafters? Also how are the ceiling jopists in the kitchen being supported laterally?

There are to many compound forces in effect with truss design to give any advice that the girt beam will hold up only the downward force of the roof load. A building permit would be required for this work and the local building opfficial wouldn't touch that one for all the tee in china. They would certainly insist on an engeineers stamped solution.

My advise: Get an engineer to design the structure properly, get a late permit, and get the engineer to sign off on the work completed. It will ensure the safety of the structure and can accompany any future sale documentation. -- Besides, the future buyer's Home inspector will certainly pick up on it and it could delay or kill the deal.
