I see you! Your german friend Cap!

I see you too your American Friend Alomo

Anatomy, in general, you have that down but more specifically you should look at some tutorials or guide books for that since you're just starting out. My stuff wasn't that great looking either, still isn't, but I look for as many tutorials on anatomy as possible to understand what I'm drawing. There's more than one way to draw out the grass or backgrounds to a picture in you're case, since you used the standard brush that comes with photoshop, you could've bunched them closer together using different hues of green and sizes.
But like I said everyone has their way of drawing and drawing when their starting out:)

Thanks I will look in to it.

You're welcome.
