Can you critique this picture please?

I got this shot in Snoqualmie, Wa.while on vacation and I absolutely love it. But what do you think about it? Can you critique it for me please? Thanks!

BTW: I'm 16 years old and have been shooting with my Nikon D5100 for about a year.

It's beautiful! I have a d5000 c: just keep taking pictures. The more you take, the more you get that you absolutely love

It's a really good photo. There's not too much going on so it's easy on the eyes. Do you have photoshop? If so, you should definitely mess with the levels. The colors are flat. You should add some more saturation and contrast, it'll bring the photo life more and give it more colors. One other thing you can do is crop the photo to where the leaf is more toward the lower right as to follow the rule of thirds. Just tweak with it a bit in photoshop, and I'm sure it'll be wonderful. Good job.

The picture is colourful and yet serene.
