It could look like a simple head swap, but it's not. In fact, when I got the Hawkgirl figure I wanted, I thought it was going to be a simple headswap, but I didn't like the way it looked. The BS Stormtrooper is a good base (among the other 6" Stormtrooper figures available), but the shoulders, chest and crotch, do not made justice to that head sculpt. I'm not experienced with customs, but I tried to do my best after disassembling the stormtrooper. Broke the interior of the torso and remade the arms support with epoxy, to place them closer to the body. I also detached the shoulder pads of the arms to reduce the width of the base shoulders. For the chest, I just cut some areas to reduce its general size, front and back. Same with the crotch, to be able to get the tights closer. Had to carve the neck area of Hawkgirl to place it in the stormtrooper, to keep the neck base. I think it looks decently proportioned and I hope you like it. I did not finish yet with her "Big Gun" that I'm making with a Hope Summers gun base, but when I finish it I will add it as my fourth picture.
