I love the coloring decisions you picked for them all, and loving the new drawing design.I decided that "board" was too similar to plank from edd ed and eddy so I had to axe that idea :/
All joking aside, here are some more fleshed out concepts (slightly) and now with potential color schemes!
I love this! The different shades of similar colors are beautiful (talking about the blue glass[?], outer dimension portal thing!), and the drawing is just as great.
"the 4 men", hahahaYou are great at drawing people, I just noticed :x The 4 men you drew are great, and they're kind of funny xD Especially the bottom right one.
