Hi guys, peter74 asked me to help him and reply if possible to questions and much more, as I followed him in this project and I am try to help him that this becomes real... Because he works very ard more than 8-10 hours per day. I know him and he made a really amazing sculpting, also he invented new technics to softening the sculpting line to obtain a shine surface so that casting will be fantastic. I know that is difficult imagine the final results of an hollow skull, but I am sure that the final results wil be what a collector would like to add in your collection. I am helping him with this project and I think that he will be able to show obtain a casted skull in about two month or so, this project needs money and the firm that will realize the casting is very expensive. anyway I really want to thanks everyone for your support.I am personally working on the electronics with lights and on the maya calendar base, probably we will be able to show the results on it before have the crystal skull done.
