heh, that went from zoobooks to mtg faster than you can blink.
i like where it is going, but there's something missing in the colors. you have red(pink), green, blue, purple, orange(brown), and that's a lot to keep track of.
my thought:
figure out your emitters and the gloss or matte qualities of each texture region, and put these lighting elements in. you've started with the lightning bolts, but they only effect the rock and they seem to have no collective light which makes them very weak. the red interior and underbelly also seems as though it should be giving off light. Once you see how things work with all the lighting tossed in, either add more colors of lights (green and red can be in your lightning, too!) and then appply those colors to the textures too to make things unified, or take away more colors in the texture as a last resort. the simpler way too without making the light psychedelic would be to just be more conservative with your colors, particularly the rock and snake body tones which can be made into at least one and a half ramps if not identical ramps (with concentrations in different ends to make the difference)
one thing for sure is that the green either needs to be more present, more important, or gone.
