Well, I meant that the different colors you have used, and there is plenty of them on each surface, are placed, I don't know how to call it, without justification. I'm looking at the second picture now, the mini from its left side. The belt and the pants have some green marks which are neither highlights, nor shadows, nor do they look like camouflage. They also do not define the color of the fabric, because the rest is just plain grey. The front of the right leg also does not give a hint where does the light come from. The armour (shoulderpads) looks like being stained.
Maybe the mini looks better in real size, here the pics are zoomed quite heavily, I don't know.
This is a style of painting where the overall impression is OK, but when it comes to details, the very things people are usually working on, ie. smoothness of the transitions, strong contrast, blacklining to define neighbouring parts - all of these are missing. That is what I meant by "impressionistic"
But the mood is OK, the guy is dirty, chaotic to the core

You don't have to change anything and you will sure find people who will love it without comments.
