Those images of Tatsu are slightly different. This image isn't for the public, It's not for making money, so it's okay to just rip anything off the net and "edit" it. It's only to show people within the company who are involved to help them visualize the project. The Tatsu images, which are actually S:UF, would have to be their own images. If it wasn't all the same company, they'd have to purchase them.
