Not a critic but just share what i think i might know and make sense of.
In the old days where statues as such are built, its artform is very much derived from symmetry. I figured based on the perspective of this image presented that you had various restrictions in your compositing of the subject. I cant really comment further cos i really dunno in which area you are presenting this piece for comments.
As a post card i think the essense of the symmetry needs to be there. thats about as much as you can do subject wise.
Hope my comments makes a little sense and helps in someways. =)
