ooooooooh, very nice! I love them! In this case I don't feel that the trees are really adding all that much other than distracting you from what you're trying to see, so I like the composition on #2 way better than #1 or #3. On #2 the trees are a very nice anchor point to help place you "inside" the photo and is definitely the best one in the series IMHO. Without an anchor point and just bare sky you can kind of lose your reference and don't know quite what you're looking at as far as scale or size. So I say #2 is perfect. Well done!
