They're both pretty, but I have to say I preffer the first one. I like that first flower is a bit further away from the camera and the little green leaf , which I think adds to it.
I really like this alot. I think the sun in the corner of this picture sets off a brilliant gleam of light to this little flower, I enjoy the angle at which the image was taken, this will have to go into my fav's. A 10/10 from me.
