To be honest, the more i look at the statue, the more i like it.The only problem is the hair.
Unfortunately hair is one of the most distinguishable charater traits on movie stars, fitional characters.
FOR EXAMPLE: in cinema, the easiest way to spot a stunt man is the variance in the hair styles. Watch any JCVD film, you clearly see where the stunt man is taking the fall (clear as day), all because of the variance in hair styles.
Bruce's hair on the CM statue seems a bit too fluffy. Spefically the front & back/bottom of his head. If this was my statue I would matte down the hair not too much because thickness must be maintained, but enough to correct the "fluffy" look.
In this picture his hair is thick and strategically placed, creating the signature "points". Duplicating this style is no easy task, but i belive it can be done.
CONGRATS!
