Frank: The Red Queen is an evil dwarven priestess actually. You got the theme though, right off. That does my heart good.
Pogre: You are always very generous with your praise. Thanks again.
As to the question of how long. I, like most people that work with Green stuff, work on several mini's at a time. I don't use a 'curing oven' so it takes a day for a particular part of the mini to cure.
One of my standard humanoid mini's is probably seven or eight steps so a little over a week of elapsed time. (sometimes many days will pass between steps though, it depends on my schedule)
Each step runs between 30 and 45 minutes. (sometimes longer)
That puts the effort at about 4-5 hours per mini.
The big trollkin probably took 3 times as long, maybe longer because of the many more steps required for such a large figure.
The mech/wizard that I used in the ENWorld sculpting project was probably about 4 hours of pure sculpting.
Game ON!
