I agree with Dru about the layout; I had to highlight the first line in order to see it. This was very sweet; I adored that ending and I certainly wasn't expecting it to happen. Even though the line might sound a little cheesy, I would be so happy if someone proposed to me like this. I adored this; it put a smile on my face. (:
I think you should move the words in the layout down a bit because the first few lines go over the picture and it's difficult to read.
I love how sweet it is, but without being sickly so. I actually didn't expect the ending, so it was nice that I didn't. I think the descriptions of both characters is well done. It's enough to give us a clear picture and the descriptions keep the story from being too fluffy because it focuses on the individuals. I love that the only dialogue is his question and the way you put that he told her she was beautiful instead of having the dialogue. It makes what he says stand out that much more.
