Ok, short review:
- I. Pink isn't my favourite color, but the skin is well done.Especially the effect of the armor shining through,as if the paint would have been applied in a hurry without much diligence
-II. The green skin itself is nice, with the same armor-shining-through-battered effect. But the marking are too similar to the one of the shocktrooper skin. A bit of variation (vertical markings, dots instead of lines etc.) would improve it.
-III.A variation of the first skin, same effect, same goodness.
-IV. An accurate shock trooper skin, but why is the shining-through-effect left out ? A bit of it would look excellent.
-V. dirt is nicely added, although there's too few color painted on the armor.The legs and the lower chest plate could need some.
-VI.Impossible to say whether it's rust or dirt : good! But the helmet is a bit ... boring and the marking on the chest plate is pixeled (?) and maybe a bit too small.
