Idk why you went with warm man? According to his breath you see on the render (aswell as the colors really) it's more of a cold base. therefore i like the BnW more then the color one. blending is good tho, aswell as depth coz of the trees.
Something about the background or overall placement is making the whole piece look 'awkward'. Maybe try and have a look @ the rule of thirds & size the render down a tad. Also, the colors don't really appeal to me; even the b&w one looks better than the colored.
