^ If I were you guys I'd ditch the idea of Apoxie sculpt - it's for taxidermists, or for use like Polyfilla (or for making fake rocks on sculpture bases). It's absolute crap for accurate detailed sculpting, trust me on this - it doesn't blend or mould well at the level of detail we're talking, like a 1/6th or 1/7th sculpt.
Instead try polymer clays like Puppen Fimo, Cernit or (what I use) Super Sculpey Firm, which is what the professionals in the sculpting biz are using. (Cheaper than two 1kg tubs of Apoxie as well). This stuff will take the finest details and stays pliable and blendable forever until you shove it in the oven, unlike Apoxie, which'll give you only a few hours' play time before it sets like concrete. I've been using Super Sculpey Firm for over a year and it's never given me problems. Ordinary Super Sculpey is okay, but I recommend mixing it with Cernit or Puppen Fimo to give it extra strength or your characters fingers and ears are prone to breaking off if someone handles your sculpts roughly.
I've got plans to make a Nelo Angelo when I get the time. Just for fun. I've been practicing human figures for while so I'm ready to try something different.
Also, I recommend using an internal metal armature for human figures like this. They just don't tend to be strong enough otherwise.
