A Lair for Shelob

My first creation in Lego Cuusoo! Well, I recently bought Shelob's Attack and I was a bit disappointed. I mean, the minifigures and the spider are great and Gollum is amazing. However, the "cave" was really small. So I began working on this and I hope that Lego consider doing it in the future.
It should come with some skeletons and bones elements, a big cave and of course the main minifigures. It would also be cool to have some orcs. Well, that's all for now. Tell me what you think.
