The picture is a bit small so it is difficult to tell. Generally it is a good idea to put the thing you are interested in about a third of the way in from two edges, it is called the rule of thirds, and ok it shouldnt be used all the time but it is often a good start for getting composition right, perhaps it would be nice to play with cropping this so as the flower ended up less in the center by taking one of the edges off, it is always good to try a couple of things like that. Have fun and welcome to the forums.
