Looks like a nice place to relax. I would like to see a little more of the bench and top of the tree. I think a little more contrast would help also. (voted earlier)
I like the composition. I don't know if you meant to put the card in the bushes, but if you put it closer to the middle it might help up the extreme texture of them.
I'm not too convinced by the lack of colour in this image purely because I like the green of the grass and the plants when I'm stressed :) I think it would have helped if you had chosen either the tree or the bench as a focal point. They're both vying for competition but neither one grabs it completely.
