Time Piece Project - Quick Sketch and Possible Idea for the Final Render

This is just a quick idea I came up with whilst in the silhouette stage of this project. The main focus of this image is going to be the floating crystal in the middle surrounded by tress in an overgrown forest. I want the image to look like the trees are drawn to its power hence the vines growing towards and over the crystal to show the Time Piece belongs there for a reason and is being protected by nature around it.
The concept of the crystal is to have a similar effect to what happens in Pokemon Mystery Dungeon or Final Fantasy 13 part 2. In Pokemon Mystery Dungeon there are these objects called time gears in each location throughout nature and each of those gears is responsible for the time flow in that location, if the gear is taken, time in that location ceases to exist. In FF13-2 there is a similar idea except there are these objects called fragments which are found in different locations throughout time and if a fragment is in the wrong time zone it creates distortions in the timeline.
