Cave Mushrooms

This is the first artwork for a little project my friends and I started a little while ago. We get two random prompts - here they were "Shortage & Formation" - and then share our results with each other after a while.
I decided early on that I wanted to do something organic and, in the end, settled on glowing mushrooms.
To get more practice with Blender, I didn't use any other software besides Blender and didn't download any textures etc. for this scene.
