Blue guy(s) vs. Space Jockey suits

I know we have been thrue this before, but I stumbled upon a picture that I haven't seen related to this question. [img]http://dl.dropbox.comhttps://scified.com/u/22357346/Prometheus.jpg[/img] I get the number of steps on the latter to be 12 and after a short Google search i know that the average distance between steps is at least .25 m (10 in). So the SJs have to be about 3 m (10 ft) and I don't think the Blue guy in the picture looks that tall. I would say that he is max. 2 m (6½ ft).
