I like it 

I see what you mean about the lighting and I'll try to do it better. Thanks for the feedback

I love the mossy facial hair.  That's a nice touch.  The lighting doesn't seem to be correct for where the sun is, though.  But that's just a nitpick.  The shading on the mountains in the background also looks pretty fantastic.  You should play with texture a bit more, though.  A statue that's been out that long should be weathered and old looking.  Put some cracks here and there and make the shading a bit less straight to give the surface an uneven look.  Maybe take some chunks out.
