Went back to basics with some thumbnails - I think taking it into a much more "pulp sci fi" direction paid off pretty well. At least I had a lot of fun doing these, instead of trying to stick to a more "realistic" design for the space suit.
Right now I'm leaning mostly towards #2 because it feels the most "action hero" like, but I like the elements of all of these guys for different reasons. Wanted to test out some more mechanical/stormtrooper looking suits (borrowing a bit from Star Wars and Fallout series with the looks on #6 and #1 especially), and also some designs that were more lithe or used rounder, more soft forms.
Any favorites for me to develop further?
