It looks pretty ok, but it could be better. I like the soft colors here.

The first thing I noticed is that everything is blured for some damn reason (most of beginner artists do that for some reason - I did that too). It looks especially weird when the leaves on a tree aren't blured. It looks much better when you have sharp and clean lines, trust me (especially in the foreground).

Another thing is the grass field behind - it could use some grass texture to not look like a flat piece of cloth (yeah, I know that it takes time, but good artwork often requires hours to finish). Also, you could divide the field into few layers (eg. 3) and the further the "layer" is from us, the more its colour blends with the sky. It gives a nice feel of perspective and it doesn't seem like it ends out of nowhere.
Here's a photo example: https://transsiberianhighway.files.wordpress.com/2013/09/dsc06274.jpg

On the same photo you can see the third thing I wanted to mention - the sky color. Since the earth is a sphere, from our perspective there's more layers of air in front of us than above us. Because of that, it's nice to use some gradient and add some lighter tones near the horizon line. The higher you look, the darker sky is.

Hope I helped somehow :)
