Its like something out of The terminator either shes going through liquefaction or shes reassembling herself. Whichever way shes going, it seems to me that there is too much metallic liquid, shes halfway liquefied or assembled and theres so much stuff still left on the ground and to me, its out of proportion. Such minor details as you point out are often better corrected in post work and its faster. Alternately you can use smaller terrains which are elongated along the y (height) axis, brought to a cone shape to start the illusion that its forming into a limb burying the terrain well inside the limb letting it flare out as it gets to the floor and then build on that using other terrains (change the terrains types in the terrain editor perhaps using Parlin Hills as a type and use clipping to make it seem like spilt liquid dropplets) and use the smooth tool to ease out the rough ridges. Here, as a quickie, I used the cone primitive scaled down then elongated along the y applied the polished silver material and a bump map. You can also use metaballs If youre using Bryce 5, perhaps with better success and with better control over their sizes. This looks interesting, would like to see where this goes.
