A Mosaic For You

Oh, it's so late already... I guess I won't have my sleep out today...
But it was worth it, I think. Well, maybe when I look at this picture tomorrow I won't be so sure about it, but...

So, what is the picture about.
Today I had an interesting dream. It was a beautiful story, and there was a scene when a boy made several mosaic pictures for a girl. Here is not that difficult variant as it was in the dream, but it was too hard to remember the exact look of it.
Also it is my first drawing with a 'plot' and a complete scene of action though there aren't too much details... And I don't really often draw in a realistic style, actually it is the second such drawing in digital ^^'
P.S. It is the boy on the picture, not the girl
And I don't know why but he turned out rather similar to me <.<
