As my bud, Ramon, once said to me...add another highlight. go that one step further, and you'll pleasantly surprised on how it looks. But, as these now look, they look flat. they need a few more highlights (or shadows) you know, that layer thing ;-) and, how about painting the toenails? (or drilling out the bolta barrels for another layer of detail?) Cheers! keep it up!
They are nice figs. I like the big wrenches. They definitely need more highlighting on the skin though. I'd yellow the teeth a bit too.
Looks like a good background set.
