Excellent work. Great choice of using 2d animation for the character. I have always wondered about using 2d animation for characters for archviz scenes since the medium tends to elicit or evoke more emotion when viewed compared to realistic 3d characters which still brings about uncanny valley. Also because the character isn't 3d, there isn't that tendency to be distracted from viewing the environment/ scene to inspecting or investigating the 3d character's movements to see if the character is real or not.
Nice artistic direction.
