Ok guys,
here's a little update on the shiny metal: First of, I decided to keep most of the outlines in 1 color, except with the antennas and spiny legs.
I found that a colored outline on the main bodies of the robots made their form less solid. With the antennas and legs it's OK, because it really conveys the feeling that they are much thinner and more fragile than the rest. But I didn't want this same feel of the metal material for the rest. Hence the outline.
The extra higlight (= rimlight?) on the right helps the metal stand out more as being metal, I think.
Then again, I might change my mind tomorrow and go with the highlight version Lendrick proposed. I've been staring at this a bit too long now. It does accentuate the dark outline, so Atnas is probably gonna spank me for that one

Note: the background by st0ven is just a placeholder environment, so don't worry about that one. I love the colors though!
Note 2: you can also see I'm working on some spaceships in a similar style. Thing is: with the shapes being so very basic and smooth, making a convincing shiny metal surface just with a few colors is a bit tedious for me. The ships have huge dark reflections. I figured: Even though they are in the same screen, actually they're in low orbit, so they should have some dark bands, reflecting space and all. I'm curious what you guys think of that.
So far... C&C is more than welcome!
