those legs may be too thin to hold up the weight of that resin body easily. sculpey weighs a bit less than plastic. if you are new to moldmaking I would reccommend making the legs as one solid piece.

the reason for this alteration is two-fold:
1) a two-piece mold is more difficult and time consuming to produce. As your sculpt already has his arms at his side, flush with the torso, this should work out perfectly.
2) the weight and balance issue. with a two-piece mold, your feet as in orig sculpt would have to be very flat and evenly spaced to balance your figure. how many figures do you own that will stand with feet in one position and tip over in ANY other? I know I've got a few (cough cough, skullcaptain, cough). it is difficult to get this right, and you may end up re-sculpting to make your legs bigger if you want to keep a two-piece mold and separate legs.
in a one-piece mold with joined legs, you only pour your silicone once, which means your mold is done and ready to de-mold your orig sculpt within 36 hours. with a broader, unified base for the legs you will greatly increase the stability of your figure. by planting your sculpt inside your retaining walls and pouring silicone over the entire figure all at once, you can save time and money on silicone. you will pour your resin into the mold as if the figure were upside down, pouring the plastic into the foot hole. the plastic resin will always dry smooth and flat, providing it is on a level surface.
sorry for the essay, but i took a class once and i like your sculpt, but can foresse some difficulties you might have in the future.
