NIce dude! cool idea and love the style! I wish it didn't fade out like that at the bottom tho, the massive arms and heavy armour make the character a bit out of place as a floating dude. also the only light source that feels like its actually part of the scene is the orangy rim lighting, and i think that if you added a few more of those but softer and above or on the other side, or even made more blue/ darker shadows it would really make this guy pop
