re: the Moon is NOT like Mars...
I agree with you in some ways...but this someone's artwork.
It looks pretty cool. Even if it's IMHO a combination of the worst parts of a hard suit and a command and control suit. I think they would be better off rendering a I-Suit with an ITMG oever it. Anyway it's not easy to make CG spacesuit people look right and I think he has done a really good job.
Besides a ITMG (Integrated Thermal and Micrometeroid Garment) would be required even in a hard suit on the Lunar surface.
