Sweet Voltage and Electric Spark Cutie Mark Cavern

Christmas present for her boyfriend ToastyDragon of his twin characters Sweet Voltage and Electric Spark. They not only have similar physical designs, but they also share the same cutie mark. So, one cave, two ponies covered. A most efficient cavern of sorts! Of course, I don't take efficiency as an excuse to justify laziness, I just gave a lot of extra little detailing here and there. This is also the first cavern to be made entirely of organic material, no rocks at all. I kinda like the fluid texture of that bark as it courses through the composition.
