Wow! the shine looks much better without the yellow hue, in the previous pic. I also like how you subtracted the dithering from the biggest crystal. Looks much smoother now. I'm guessing the lower crystals in the center are still a work in progress, as they still seem chunky, and undefinable at some parts. Not as geometrically defined as the upper portions is what I'm basically trying to get at. Also, the detailed crystal being so smooth, now creates a problematic consistency with the rest of the piece; the crystal is so wonderfully done, and smooth, yet the rocks towards the right look very unfinished. I'm just wondering how you'll pull off the smoothness of the water with the light source and ripples...
Again, this is probably still a work in progress, so I'll hold my tongue for now. Looking great though...
