The size of this character does vary. However in the comics he sits at somewhere between 3'8"and 5'2"
In JLU trial of John he is waist high to arkis chumunk who is the same height as Hal. also if you go look at his stats his height in the Who's Who which I have he is 4'2" which is some where between waist and chest. But Like I said awesome fig. I have done this one my self and he is no cake walk.
I also have to say I love the expression the hulk head gives to him.

The size of this carrecter varies. In the green lantern first flight movie he was quit large while in the JLU cartoon he was about the size of a basketball.

I can do that with hot glue. Thanks fore the goold suggestion.

Nice Job very good look I only have one problem he is a tad small. The character should be at least waist height on hal jordan. But this is Difficulkt but otherwise I have to say love the fig.

darn, you should be proud of yourself! Excellent green lantern mates. The thing that would set him off, is if you added a sparkle of bursting flame to his ring. Like a piece of flame from the marvel universe line. Other than that, very cool!
