Its a bit soft, having said that it might be improved by using a tripod. You did not give out that info. Perhaps a little tweak to the ISO, aperture, or shutter speed or a change in all three. Looks like some back lighting going on there also, a white piece of cardboard or reflector in front of the subject might help. Photography is an art I find challenging sometimes but very rewarding in the end. Keep up the good work and by all means...keep posting.
That is a really nice flower image. I find the sharpness to be quite nice at full size. About right for my taste. The only changes I would have made would be to clone out the little hair or something at bottom right and the white band across top left. They are both distractions which would improve the image if they were not there. But, regardless, it is very pleasant.
