@EdJr- Aw, thanks! Some day I'll upload something not cute 
Maybe after the voting is over I'll come back to this and fix some things/finish this.
How do you manage to make everything look so cute? *-*
I don't think it would make a lot of sense to make those crystals brighter; it's actually quite the opposite (the cave is too light). But it would make even less sense to use too dark colors in a piece like this.... So, it's pretty good as it is! Voted on you with my eyes closed.
@Zizka- Oh, but I did make the deadline! I turned it in on time, it's just not as polished as I'd like. And thanks!
Too bad you missed the deadline, smells like victory to me.
@DragonMarx- Thanks!
@Daruda- Yeah, I like bright, soft colors which don't lend themselves to dark caverns very well. Could have used a more appropriate palette 
I like the scene and the mole is lovely.
It's only me or the cave is too light? D:
@ Suusi- Thanks for the comment! I was following the thread in the forums, which made me feel like this piece fit the criteria. I thought of it as more of a geode cut in half than an architectural plan. If they feel that it doesn't fit, the moderators are free to remove this from the challenge.
Thanks, guys! The crystals are pretty dark, I was going to give them a pulsing glow as well as animate the mole, but I ran out of time 
Also wish the crystals had more pop to them. Great submission though, I kind of wish I had caught onto this challenge. This one probably getting one of my three votes.
Nice work and nice animation, I think the crystals should be brighter, though you may have been running out of colours. :)
Charming little piece!
