I think numbers 1 and 2 are really strong photos. My favorite is 2. The subject is framed really nicely, the colors are vibrant, and there is movement in the photo. I like 1 because the colors in the sky work well with the silhouette of the tree. If I did anything to change that picture, I'd darken the blacks just a tiny bit to add the focus to the tree and the sky, and not what's going on under the tree. 3 could've been taken a little differently to add dynamics in relation to the background. Maybe take that one at a different angle next time. Try to emphasize the spider web.
You have a LOT of really nice photos on your Flickr account, especially on the first page. It definitely takes talent to be able to work with both still-life and portraits.
