Not bad, nice and sharp and colourful. Just watch the crop - in the first one you have cropped that part of the flower sticking up (stamen?) - I am not a biologist, by any means. In the second one, you have cropped a little tight on the top and the same with the third on on the top right. Give the flowers a bit of "breathing" room. Also, if you would number your images in future postings, it makes it a lot easier for reviewers to refer to an image if it is numbered - thanks.
