Almost finished the dome , I compare with spfx dome and return of Jedi gs helmet , use them as reference of my sculpt , helmet flare in hasbro it’s fine 30 cm , same as spfx and Jedi dome , main problem were the dome lack of volume almost 4 to 5 cm in top and sides probably 2 cm , I add lots of bondo , first I use aluminium foil paper , then hot glue to surface gave overall volume bondo on top of that , so I didn’t have to use double the amount of bondo , I was researching for the Jedi helmets and the neck on the reveal from ilm it’s indeed the shortest , but several other helmets was used in Jedi , and neck vary in couple of them , my neck it’s larger , maybe I’ll fix that latter , back to the dome , I almost finish the sculpt, most of the proportions are now ok but not perfect I try to maintain asymmetry sculpt in it, since original domes are asymmetric , mine helmeit’s not perfect but much better than the original hasbro sculpt, when I finish the helmet I will post some photos also I will put it inside the original box to see how that fit, these helmet it’s pretty cool for a toy and a nice project to work, dome also should be repositioned higher , as Jedi domes were higher , thanks , First photo it’s ilm original reveal helmet, second and third are Mark Cfo return of Jedi helmet I compare distance from chin triangle to neck , I know it’s some angle distortion from images but I think my neck it’s a little bit larger will trim that after finish the dome ,
