The drag-in is cool, however when image is on a 45 degrees wall like this, the perspective is often slightly wrong, and there's no way to do a free transform mesh (like adjust one of the four corners) to match it. Also sometimes there are some rough edges at the border of faces, and getting more annoying when there is some blur object in front of it (like a plant). Might just need time to optimize the algorithm, the experience is still amazing.
