Welcome M. Nice job you did.

But I have a question. Did you take the shape of the terrain into account? In that photo I don't think they are standing on flat ground. I believe they are in a bit of a depression, where the shadow of the astronaut on the right is stretched out on a downslope, but the one on the left is on an upslope and thus foreshortened. That might have a bigger effect on the shadows than the type of lighting used.

At least I think so. Jay or someone may be able to help us out here?
