Fallen leaves on the ground [ended]

No, this is not a Billy Talent puzzle. It's literally about fallen leaves on the ground. Had the idea for this when I walked the dog -- autumn/fall is really beautiful over here. Well, as long as it doesn't rain all the time. We've been lucky this year.

So here's the puzzle! I guess it will be easier for people from Europe and North America, but it should be solvable for everyone with a little googling. (But don't waste your time googling those images, I took them myself.) I learned those leaf shapes in primary school, I'm sure you can find helpful charts and stuff.

Feel free to ask for hints, I'll try to be helpful. I don't want this to be hard.

Oh, and have some mood music! (Again, not Billy Talent.)

Usual rules apply. Don't share any solutions, blah blah.
