This is so nice! But one thing I think you should think about it cropping the part of the tree in the bottom right corner. I think it's somewhat a distraction.But the colors are good and I like the one bird flying. Nice job.
The swirl of the clouds, the gull, the silhoutte ... all do good things for this pic, even though its not one of the great ones, it's one of the better ones.
I like how there's a soaring bird in the corner, but I suppose that was coincidental. I wouldn't have included the leafy things in the botton right corner.
Good blocking out of the sun by the branch. Liked the birds. Gives it perspective. Didn't like the corner of the tree in the lower right corner. Still all in all a nice interpretation.
If it weren't for the bush in the lower right this would be a knockout (at least in my opinion). Love the branch and the bird simply adds interest. Very nicely done.
