Fire Golem Concept art for Action RPG/Hack and Slash

Hey, guys!
I’d like to present you my new project - a series of Golem creatures.
The third one is Fire Golem. You could check Ice and Earth golems in my previous artworks.

There is a gorgeous volcano in front of you, ready to erupt. Ground turned into grey. There are no creature within a hundreds miles around. An entrance is blocked by a 20-feet high stone. But suddenly a lumps of coal began to slowly form into a monster. His body is seething with lava. His arms are swinging around, erupting flames and ready to burn you into ashes. Stones are crushing around you.

This is the Fire Golem. A last challenge that remained between you and your goal...
