They both look very good. The flower one is very good, but something about the boked is very unusual, albeit in a good way. I don't know if it's the web compression or something else, but the leaves are almost doubled, or have a slight halo to them. I think it works since it makes you think twice about it.
The second is very impressive as well. I love the gradient that with trees they are looking down upon in the foreground and ends in the washed out sky. Compositionally, I think the tree in siloheutte to the right makes the frame a little "heavy" in that area, but that was not something I noticed until a second glance.
All in all, very good pictures, have any more? Were you using a Canon lense?
