Thats pretty cool, like the colourscheme very striking, just at times looks a bit plain, especially with the sword being the same colour as the armour but still it ties in really well.
It looks like there are two light sources, one from the lava, and one from above. That\'s well and fine, but the lava is reflected on top of his left boot, which doesn\'t look quite right to me. Otherwise, very good job with a limited pallete.
