Help me improve..

I made this quite a week ago. I think it lacks something. I just don;t know what.

Is that a rock?

Or a whale?

Or maybe a rock whale? Anyway, the grass on the left side of the palm is too low, which looks silly. Furthermore, the blue in the background lacks something. I just don't know what.

The Sky is too uniform, too all one color. You should have darker blue at the horizon and lighter shades as you go up.

Actually, if you look at photos of a real sky, you'll notice that it tends to be the other way around.

The picture has foreground and middleground, but lacks a background layer. Show something, anything in the distance before going back to the sky. Another line of hills is the obvious, but not necessarily most interesting choice.

The big white things (clouds?) and the huge tree clutter up the picture somewhat. Try making them just a mite smaller.
