From what I see in the photos this looks like a good job. The bricks used on your walls are available in Thailand but regional in their use.
The header and stretcher brickwork on the walls is extremely strong and with these bricks provides quite good insulation value. Bricking to the columns full width is a good choice as it not only loses the columns but adds a nice reveal to window and door openings.
If the architect of this project had considered the load bearing capability of your walls you would probably be missing a few columns.
