The design of the set is very nice.
There is so much potential with this. It just needs some more shading and color. For example, the circles on the legs could be made into crystal stones, and shading would add the depth it needs to be truly EPIC.
I hope that you get the time to spice it up. (you'd get so much more money for it too)
Anyway GL on the set.
ps, recoloring to black and white is one of the easiest recolorings you can do. Even easier since you don't have any shaded spots, so the color is the same throughout the texture....
