1. The colors are dull and the lighting poor. The focus of interest is a bit lost to me. Overall not an interesting picture at all.
2nd one has better potential. The colors are a little more vivid, but what I would think is the main subject of the picture, is dark and barely in focus. The picture looks a bit blurry to me.
It looks like you used an old and half dead flower and the lighting was really uninteresting.
My suggestions: Use a fresh flower, in good light. Decide up-front what you want as a the main focus point in the picture. To me, withering flowers can make very interesting subjects, but half-dead ones like this, are just that. Half dead.
I hope I haven't discouraged you, that's not my intention at all

You're the one who asked for c&c and actual comments are of more use than either silence or short-worded comments (in my opinion at least).
