No offense, Jedster, but I am kinda hoping that your tendency to like the Bandai version gave you a skewed perspective on the HT Batmobile. You mentioned that you liked the curvature to be exaggerated as they did on the Bandai and I am hoping that seeing the HT in that scale skewed it for you. Then again as an artist, you probably have a good sense of proportions.
Right now i am hoping you took some pics of the batmoible while at the con and can do a comparison photo with your maquette to see the differences are.
On a strange but really happy note a friend of mine, for some reason decided that he couldn't do anything with the Richmans' toys version of the RC 89 batmobile. Never been played or displayed, box has wear and tear; but Jeez louise how lucky am I?
