Welcome from me too Grace.
I see your entry is a horizontal shot of a flower and background isn't it? I could suggest you a vertical framing, like you would do with a portrait. But what I can distinguish in your picture is more than that. I see the chance to admire the beauty of the Nature, to be taught about the mixing of the colours, I see the capture of the fleeing moment on the blow of the wind , which you have so nicely recorded.
I would ask you to increase the zooming of your browser to 200 and look closer at the centre of the flower. Your frame can be oblong or square; the picture now focuses on what it really matters, the flower itself. Can you see it? There is no more green around the flower, but only a tiny bit, where the petal is shifted by the wind. Admire how nicely the blue/lavender colours of the centre of the flower mix with the orange/brown parts around the flower centre, how nicely the purple colour is hued from the beginning of the petals outwards; the ends of the petals can be omitted.
There could be various ways you could achieve this ''zooming'', a reversing of your lens, a stronger zoom lens, or a x3 magnification glass, or some extension rings; but the most important of all is to be able to focus your attention where it matters
