Having trouble coming up with something to draw? No worries - while you'll eventually learn how to start from a tiny seed of a thought and gradually nurture it into a complex concept to explore through design and illustration, it's perfectly fine not to be there just yet.
For now though, here's an idea that might interest you.
For too long, the fae have lived in pitiful hovels, their accommodations cramped and unfit for beings of their majesty. No longer!
There have been whispers upon the wind of a great fairy architect who's been building great fortresses, palaces, and mansions, and now not one of the fairy host will tolerate anything less. But there are many among the fae, and few of them equipped for such a task.
And so they've crashed through your bedroom window, gathered up your paper and crayons, and thrust them upon you as you slumbered. "We demand comfort! We demand luxury!" they cried in unison.
It would be unwise to deny them, so you'd better get to work. Design a house - nay, a palace - for your nighttime interlopers, and be sure to use lots of natural structures and materials. Dirt, flowers, grass - and a variety of mushrooms to be sure!
