I like clouds because i like how they look (all of them), and they are fun to draw. ^_^
Trees are also fun to draw... and mushrooms!
Oh, and smoke... Water is fun too.
Oh yeah, I like big, clean, large bodies of water. I always feel taunted if a game has a beautiful beach/lake/river and won't let me go in it. D:
Edit: Ah, okay. I wasn't sure since I didn't see anyone with 500 posts. Only 600+ or 400-something and below.
