OK. I went back and looked at the figure again in the Gallery and I do believe that it IS the pose that's throwing the whole statue off (at least for me). Because of the awkward angle of it (or it could be the remarkably poor lighting choices), the statue looks really top heavy, like Hal's bigger from the waist up than he is from the waist down. I realize this is likely just an optical illusion, but it is there (again, IMHO). If you factor in the fist construct, then his top half looks even bigger!!!
As far as the shiny aspect goes, I don't mind it, but I wish they would have confined the shininess to the green and white parts of the uniform and left the black parts as really ultra-matte black, which would have really made the green and white pop!
Another thing they could have done that would have really amped up the "cool" factor was include an attachable "floating chevron" you could put on the figure along with the construct to indicate that he's using his ring, much like Ethan Van Sciver and Ivan Reis had his chevron levitating about his GL symbol in the comics...
