This is truly minimalistic. Love the minimal pallette..the stark black against the smooth gray sky...very pretty. It reminds of an ink drawing...love the title.
The kissing birds is a very good accent to this picture. The background could have benefited from a more uniform tone. There appears to be too dark of a grey on the right side. Also a little bit more cropping on the left to remove those upper branches would be beneficial.
The title and the necking birds make a cute combination. The tree breaks up the monotony without drawing the eye too much or being too distracting, which is good. The overall effect is good, but not really spectacular, though there's nothing technically wrong that I can point to. 8.
