Lovely work, Claudia. I especially enjoyed your "Time Warp" pic.
A tip: the vanishing points in any two-point perspective should be on opposite sides of the viewer. In ?The Kinnaree's Love" and in "Grown-up Now!," the right-side vanishing point (for the floorboards) should be located off to our right, outside of the image, to avoid giving the floorplane a slanted look.
