I ordinarily don't like photos taken from directly above a flower. Photos like this will always look 'nice', simply because flowers are beautiful, amazing things... But there isn't much interesting or creative about pointing your camera directly down at a flower and clicking the shutter. I've noticed some photographers whose portfolios consist only of head-on flower shots... Booooring. Sometimes I do succumb to the temptation to take these shots, though... and sometimes they do turn out alright, especially if I'm able to get in very close, with the light shining through the petals.
