A tree in the City

This is an amazing picture combined with seemly plain stock photos! I, myself, don't use stock photos (in fact barely), but I always find myself awed at how people can create such beauty with stocks alone.

I love the sky and how it's a mix of blue and orange and how the tree perfectly rest on a skyscraper as if it had been there all this time. I like how you added more details to it by having birds in the background. This picture gives you a feeling of serenity, yet mysterious. I don't know what else to say you can do to improve on it, so great job!
