When I shoot my realistic shots, as opposed to the eBay type shot, I am shooting with model on a card table, and since I am using around f/32 or so I can let the bottom of the lens hang below edge of table to get down to scale eye height. I figure about five foot is normal eye height.
Magazines seem to like those eBay shots, so I do sometimes shoot those. They are characterized by a higher camera angle and flat lighting.
My realistic shots are shot with a backdrop of aprons of airports. I got tired of driving to airports every time I wanted to photograph a new model, so took shots of airports in area to use as backdrops. I distort portions of the apron and/or runway to produce a surface to place the model on. I shoot from scale eye height, and shoot in sunlight ( shoot all the backdrops in sunlight). I think the enhanced contours and highlights are a bit more realistic than with the flatter light.
Here is a sample of what I get.
