Hi Charlotte,
It's a nice image with good highlights. But since so much depends on these highlights the petal behind the flower really distracts from the flower. It doesn't add anything to the interest of the image, it is just there.
It would be worth trying to reshoot the image without the extraneous petal. If not possible, simply clone it off and see how the image looks then. If I am correct it will be stronger.
I'd also clean up the semi dark line horizontal behind the flower while you are at it.
This is sort of a studio look image, and I think it calls for as clean a rendition as you can make it
It's quite common that the photographer loses sight of the main subject when starting out in photographing a new subject. Here the main subject is the blue flower with a yellow trumpeted base, not whatever is going on in the background. That detracts from looking at the quality highlights and color of the flower.
It'd be also worth trying to photograph the entire flower as Ron suggested. Only by comparing this version and a full-flower version can an educated guess be made regarding which one is the stronger composition. I agree that this is sort of different and "non-cliche" as you say, but that doesn't mean it is stronger. I recommend working towards stronger first then different second. Of course if you can do both stronger and different then great. However, this is more difficult.
