Picture 1: I guess in this photo you're main subject was flower on that piece of wood. If its true then this photograph is not taken well. There are lots of which that are begging my focus. You must have cropped in such a way that only wood and flower are there in frame. Just a thought! Everything else is fine. There are variety of colors brown in contrast with green is looking great!
Picture 2: Over exposed light in the background. If there were no cars in the background then would have been better picture. Apart from that No flaws! I love this photograph specially, that disposal glass. It's telling me that some had coffee there while sitting on the platform under the tree. Seems like lot had happened over coffee.
Picture 3: Perfect click! Perfect!..
