I was happy to obtain a Demon Prince box recently from my buddy Kevin (http://myworld.ebay.com/teachermickeymouse/?_trksid=p4340.l2559). I like the box only because I can see some potential if it's modified. The kit itself looks a little bare to me, like the sculptor never went back and added that third layer to the piece.
So I've gone about adding a great amount of putty to the kit after I hacked and slashed it a bit. Mainly minor changes to the angles of his limbs.
Here he is after the first layer of sculpting.
Once this was dry I added a second layer with a little more detail.
That's as far as I've gotten on him so far. One or two more passes with the putty knife and he should be ready for some paint :)
