Don't really care about the other versions but the JP1 look. Please make it look like it's alive instead of just a open or closed mouth "pose" with zero neck or hints of the eye movement. All the recast pieces(fully finished) out there looks boring and.."DEAD".
Please take the time, play with the casting, make whatever subtle changes that needs to be done to make it look like it's ALIVE. If you want the mouth to open, then open WIDE with drools and all the other element to make it work. Want closed, then it has to be with a certain expression, especially the subtle changes around the mouth and and around mouth area.
Last but not least, please pick the right materials for the eyes. You can do it! Surprise us~
If you guys nailed this one. The other versions will be benifit greatly from it. The idea also applies to the 1/5 female T-Rex bust also.
