The main element (crocus) is too blurry, where the background could be more so (and a lot darker to "pop" the bloom. I also might have cropped away the right side (to eliminate the extra leave.)
The flower petals seem a bit overexposed as if there was too much flash used and not enough natural light. Love that you've captured just a touch of the purple and yellows peeking out of the flower though.
3 - Better focus and a more finely tuned crop and more balanced composition, make this better in my opinion. Given you've photographed something white, over-exposure is easy to do, which seems one of the main problems here.
I've seen a lot of plants and trees... Yes, they meet the challenge, but where is the creativity... It's the image that stands out from the rest that wins me over.
