I tried a few variations on the blue guy above, but the best thing I got out of it looked too much like the Predator. So I decided to ditch that one.
Here's a new head I came up with, one I quite like and might actually stick to it. Still needs some more refining but I like where it's headed.
Variation on the face/head:
Variation on face armour:
From the first bunch I like #5 the most and might stick with that idea, though I'll revisit it some more and work the horns a little.
From the second bunch... I only like #2, the rest are pretty shit.
I might combine the two I like and do a few more tweaks here and there and see what I can come up with. Though I'll be doing some body concepts tonight.
C&C welcome... Paintovers too if anyone has any ideas for the heads or face armour.
Thanks in advance for any comments.
