Thanks you for comment! I will try shade more some areas to create more contrast, but I didn't yet becouse I'm not shure where exactly do. And I want more purple shade in the skin but I want not a very dirty or unclean paint sensation, and I'm thinking how to do.
Very nice work. Clean, simple, but with some nice flourishes (such as the freehand skull on the helm, and the rust on the axe). Perhaps some contrasting colours used in the shading would have made the model a bit richer and more natural looking? A dark brownish red in the recesses of the green armour, and perhaps some dark purple washes in the creases of his skin would have really made this model pop.
