1, the cat has a great expression! I think though that the Highlights are a bit blown above his head, as You lost the detail in the fur, cropping portrait orintation may have been better too. The eyes seem nice and sharp which is good.
2 Ilike the perspective idea on this picture, the skyagainst the plant looks good, there does seem to be a strange halo around the flowers, -was the wind blowing? maybe its from movement and the flash? I dont know as I m a newb at this still.
I hope thats useful
